Answer:

C. 1 day

Step-by-step explanation:

Chris:

10 - 4d

Evan:

8 - 2d

How many days will it take before they both have the same number of bags remaining?

Equate both expressions and solve

10 - 4d = 8 - 2d

Collect like terms

10 - 8 = -2d + 4d

2 = 2d

Divide both sides by 2

d = 2/2

= 1

d = 1 day

It will take 1 day before they both have the same number of bags remaining

Hayley is buying herbs. She wants to buy 5/6  ounce of basil. The scale she is using to weigh the basil displays the weight as a decimal. How will she know when the display on the scale is correct to the tenths place? Explain your reasoning.

Answer:

0.8

Step-by-step explanation:

To obtain the fractional expression of weight in decimal form:

5/ 6 ounce of bassil is converted into decimal :

5 / 6 = 0.8333

Hence, for a fraction of 5 /6, we obtain;

Answer:

x =-18

Step-by-step explanation:

5(x + 9) = -45

Divide each side by 5

5/5(x + 9) = -45/5

x+9 = -9

Subtract 9 from each side

x+9-9 = -9 -9

x =-18

Answer:

The correct answer is x = -1.

Step-by-step explanation:

Step 1: 5(x + 9) = -45 <----- This is the original problem.

Step 2: 5(9x) = -45 <----- Add the variable.

Step 3: [tex]\frac{5(9x)}{5} = \frac{-45}{5}[/tex] <----- Divide both sides by 5.

Step 4: 9x = -9 <----- Simplify

Step 5: 9x/9 = -9/9 <----- Divide both sides by 9.

            x = -1

The required inequality is:

[tex]\mathbf{x >60\: and\: x<135}[/tex]

Step-by-step explanation:

Minimum Money students should bring = $60

Maximum Money students should bring= $135

We need to write compound inequality  that  represents the amounts of money a student can bring.

Compound inequalities are combination of two inequalities combined with "and" , and "or"

And is used, when both inequalities should be true.

Or is used when one of the inequality should be true.

In our case we would use and because we need  both inequalities to be true.

The cost of one taco is $3.75.

We are given cost of salad, the sales tax and tip along with total expenditure. We already know, that sales tax is calculated on the cost of items. Hence, forming the equation accordingly. Let us assumed the cost of one taco be $x. So, the cost of two tacos will be $2x.

The equation will be -

2x + 2.50 + (2x + 2.50)×(6÷100) + 3 = 13.60

2x + 2.50 + (2x + 2.50)×0.06 + 3 = 13.60

Now, solving this equation to find the value of x and hence the cost of one taco.

2x + 2.50 + 0.12x + 0.15 + 3 = 13.60

Performing addition on Left Hand Side

2.12x + 5.65 = 13.60

Shifting 0.18 to Right Hand Side and performing subtraction

2.12x = 13.60 - 5.65

2.12x = 7.95

x = 7.95÷2.12

Performing division

x = 3.75

Thus, the cost of one taco is $3.75.

Answer:

x ≥ 10 or x ≤ -8

Step-by-step explanation:

2|x - 1| - 3 ≥ 15

Add 3 to both sides;

2|x - 1| ≥ 18

Divide both sides by 2

|x - 1| ≥ 9 or |x - 1| ≤ -9

x - 1 ≥ 9 or x - 1 ≤ -9

Add 1 to both sides;

x ≥ 10 or x ≤ -8

Answer: 4z + 3

Step-by-step explanation:

Number of books read by Zeke = z

Michelle read twice as many book as Zeke. This will be: = 2 × z = 2z

Tay read 3 more books than Zeke. This will be: = z + 3

The expression that represents the total number of books read over the summer by Zeke, Michelle and Tay would be the addition of the books read by each person. This will be:

= z + 2z + z + 3

= 4z + 3

Answer:

7x+18

Step-by-step explanation:

add both 4x and 3x to get 7x and add 10 and 8 to get 18. therefore 7x+18

The final expression of (4x + 10) + (3x + 8) is 7x + 18.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(4x + 10) + (3x + 8)

Combine like terms.

4x + 3x + 10 + 8

7x + 18

Thus,

The final expression is 7x + 18.

Answer:

All of them except for the 3rd one

Step-by-step explanation:

2) 15 - 3x = 5(x + 4) - 8x

15 - 3x = 5x + 20 - 8x

15 - 3x ≠ -3x + 20

4) 2(x - 7) = 2x - 10

2x - 14 ≠ 2x - 10

1) 24x - 22 = -4(1 - 6x)

24x - 22 ≠ -4 + 24x

3) 12 - 2x = 6(2x + 2)

12 - 2x = 12x + 12

0 = 14x

0 = x, only one that has a solution

The algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.

The Commutative Property of Addition is an algebraic property that states that the change of arrangement or order of an expression does not change the sum of the expression.

For example, based on the commutative property of addition, a + b = b + a.

In the same vein, if we have 12 + 4x, then 4x + 12, it means that whichever way we choose to order the operation, the sum remains the same.

Therefore, the algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.

Answer:

B

Step-by-step explanation:

Only one in which x is not more than one number matching y in function.

The table 4 represent the function.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

The function should have distinct input with corresponding output.

If there are 2 same input vales then it not said to be a function.

So, according the definition the table 4 represent the function because the table 1, 2 and 3 have repeated input value,

Hence, the table 4 represent the function.

Answer:

a

  [tex]P( \^ p > 0.775 ) = 0.12798[/tex]

b

 [tex]P( 0.6718 < p < 0.775 ) =0.87183[/tex]

Step-by-step explanation:

From the question we are told that

    The population proportion is  [tex]p = 0.75[/tex]

Considering question a  

     The sample size is  [tex]n = 387[/tex]

Generally the standard deviation of this sampling distribution is  

         [tex]\sigma = \sqrt{ \frac{p(1 - p)}{ n } }[/tex]    

=>      [tex]\sigma = \sqrt{ \frac{0.75(1 - 0.75)}{ 387 } }[/tex]    

=>      [tex]\sigma = 0.022[/tex]    

The sample proportion of cans that are recycled is

                 [tex]\^ p = \frac{ 300}{387 }[/tex]

=>              [tex]\^ p = 0.775[/tex]

Generally the probability that 300 or more will be recycled is mathematically represented as

         [tex]P( \^ p > 0.775 ) = P( \frac{\^ p - p }{ \sigma } > \frac{0.775 - 0.75 }{ 0.022} )[/tex]

[tex]\frac{\^ p  - p }{\sigma }  =  Z (The  \ standardized \  value\  of  \ \^ p  )[/tex]

       [tex]P( \^ p > 0.775 ) = P( Z > 1.136 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1.591   is

      [tex]P( Z > 1.136) = 0.12798[/tex]

=>    [tex]P( \^ p > 0.775 ) = 0.12798[/tex]

Considering question b

Generally the lower limit of  sample proportion of cans that are recycled is

                 [tex]\^ p_1 = \frac{ 260 }{387 }[/tex]

=>              [tex]\^ p_1 = 0.6718[/tex]

Generally the upper limit of  sample proportion of cans that are recycled is

                 [tex]\^ p_2 = \frac{ 300}{387 }[/tex]

=>              [tex]\^ p_2 = 0.775[/tex]

Generally probability that between 260 and 300 will be recycled is mathematically represented as

           [tex]P( 0.6718 < p < 0.775 ) = P( \frac{0.6718 - 0.75 }{ 0.022}< \frac{\^ p - p }{ \sigma } <\frac{0.775 - 0.75 }{ 0.022} )[/tex]

=>      [tex]P( 0.6718 < p < 0.775 ) = P( -3.55 < Z < 1.136 )[/tex]

=>        [tex]P( 0.6718 < p < 0.775 ) = P(Z < 1.136 ) - P( Z < -3.55 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1.136 and  -3.55  is

       [tex]P( Z < -3.55 ) = 0.00019262[/tex]

and

       [tex]P(Z < 1.136 ) = 0.87202[/tex]

So

       [tex]P( 0.6718 < p < 0.775 ) = 0.87202- 0.00019262[/tex]

=>   [tex]P( 0.6718 < p < 0.775 ) =0.87183[/tex]

Answer:

-7/2 or -3.5

Explanation:

The slope is rise over run.

The rise is how much it went up and the run is how much it went right

The line went up 7 units while going -2 units to the right (meaning it went 2 units to the left)

This makes our slope 7/-2 which is the same as -7/2 or -3.5

Answer:

The larger wheel is 10979.04098 more than the smaller wheel.

Step-by-step explanation:

Given that,

The circumference of the great wheel was twelve thousand and forty-one thousandth inches.

C = 12000.041 inches

The circumference of the lesser wheel was only one thousand twenty-one and two hundred-thousand inches.

C' = 1021.00002 inches

We need to find how much larger was the great wheel. To find it, take the difference of C and C'.

C-C' = 12000.041 inches - 1021.00002 inches

= 10979.04098 inches

Hence, the larger wheel is 10979.04098 more than the smaller wheel.
