• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.

• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.

• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

• When we are not given a number for the variable in the expression, we have to group like-terms.

1. 4x + 12 - 3x + 8

2. -8x + 1 + 2x - 1 + 6x

Answer:

The slope of the line = m = 2

Step-by-step explanation:

Given

The points

To determine:

The slope of this graph

Determining the slope between (0, 0) and (1, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 0] / [1 - 0]

               = 2 / 1  

Thus, the slope of the line = m = 2

Answer:

19.75%

Step-by-step explanation:

Since we are trying to find the probability for a sequence of events then we need to multiply the probability of each event happening separately from each other. Since the probability of it raining on a single day is 2/3 we need to multiply this value with itself 4 times (one for each day).

2/3 * 2/3 * 2/3 * 2/3 = 16/81 or 0.1975 or 19.75%

Therefore the probability would be 16/81 or 0.1975 or 19.75%

Answer:

16 $10s & 1 $5

Step-by-step explanation:

16 × 10 = 160

5 × 1 = 5

Answer:

Step-by-step explanation:

Let amount of water in lbs is x

so, mass of solution = mass of water + mass of sugar

= (x + 0.5) lbs

concentration of syrup = mass of sugar/mass of solution × 100

75 = 0.5/(x + 0.5) × 100

or, 75/100 = 0.5/(x + 0.5)

or, 3/4 = 0.5/(x + 0.5)

or, 3x + 3 × 0.5 = 4 × 0.5

or, 3x + 1.5 = 2

or, 3x = 0.5

or, x = 0.167 lbs

hence, amount of water is 0.167 lbs

Answer:

0.167lbs

Answer:

When subtracting expressions, we are applying the distributive property, where a multiple of an expression in brackets is applied to to each term.

e.g.

a(x + y) = ax + ay

In the case of subtracting an expression, we're doing the same thing, but in the example above, "a" would be equal to -1.

(a + b) - (c + d) ≡ (a + b) + -1(c + d)

And so the negative one is distributed across the terms within the brackets.

Hey there! :)

3t - 18 = 4(-3 - 43t)

Let's start on the right side of the equal sign by multiplying "4" with everything inside of the parenthesis. Keep in mind that a negative times a negative is a positive & a negative times a positive is a negative.

Let's put this all together:

3t - 18 = -12 - 172t

Now, we need to isolate "t." We can do this by adding 18 to both sides along with adding "172t" to both sides.

3t - 18 + 18 + 172t = -12 - 172t + 172t + 18

Simplify.

3t + 172t = -12 + 18

Simplify - add like terms!

Let's put this all together:

175t = 6

Divide both sides by 175.

175t ÷ 175 = 6 ÷ 175

Simplify.

175t-18=-12

Step 4

175t-18=-12   Add 18 to sides

175t=6

Step 5

175t=6   Divide sides by 175

Answer:

45440

Step-by-step explanation:

32,000*6*.07=13440

13440+32,000+45,440

The amount we have to pay at the end of the 6month period will be $33,120. The rate of interest on the loan is given as per annum and therefore; the interest is to be calculated for 6 months.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.

Simple Interest = (Principal × Rate × Time) / 100

Calculation of settlement amount of loan:

Given:

Principle= $32,000

Rate= 7%

Tenure= 6 months

Interest is calculated from the following formula;

Interest= Principle x rate x tenure

Therefore the interest for the loan will be;

Interest = $32,000 x 7 x 6 months

           = 32,000 x 7/100 x 6/12

           = $1,120

The final payment for the loan will be the combination of principal and interest.

Therefore final payment = $32,000 +$1,120

                                         = $33,120

Answer:

x = - 4

Step-by-step explanation:

First do distributive property

5x-15=10x+5

then add 15

5x=10x+20

-10x

-5x=20

divide 5

x=-4

Answer:

x = -4

Step-by-step explanation:

5(x−3) = 10x+5

5x−15 = 10x+5 (Simply both sides of the equation)

−5x−15 = 5 (Subtract 10x from both sides)

−5x = 20 (Add 15 to both sides)

−5x /−5  =  20 /−5  (Divide both sides by -5.)

x = -4

Answer:

Answer:

2, 4 6 and 8

Step-by-step explanation:

Given the range of a function expressed as ƒ(x) = -6x + 11 where x are the values of the domain

Given the follwing range f(x) =  {–37, –25, –13, –1}, we are to find the corresponding value of x;

-37 = -6x + 11

-37 - 11 = -6x

-48 = -6x

x = -48/-6

x = 8

if f(x) = -25

-25 = -6x + 11

-6x = -25-11

-6x = -36

x = -36/-6

x = 6

if f(x) = -13

-13 = -6x + 11

-6x = -13-11

-6x = -24

x = -24/-6

x = 4

if f(x) = -1

-1 = -6x + 11

-6x = -1-11

-6x = -12

x = -12/-6

x = 2

Hence required domain values are 2, 4 6 and 8

The expression of the Earth 1.496 x 10^8 km  in standard form is 149,600,000

Standard form is a simple way of expressing very large numbers into small sizes for easier calculation.

The given information is already in its standard form as 1.496 × 10⁸ km.

We can express it in its ordinary form by shifting the decimal place to the right side in terms of the power with which it is being raised.

Answer:

Step-by-step explanation:

14.25/5 is 2.85

Answer: 17/60

Step-by-step explanation:

Suppose that whe have N fishes.

We know that 1/5 of these N fishes are guppies.

We also know that 1/12 of these N fishes are goldfish.

Now, what is the fraction of guppies and goldfish together?

We only need to add the fractions:

1/5 + 1/12

This may be hard because the denominators are different, then the first step will be to write both fractions with the same denominator.

We know that:

5*12 = 60

Then we can write:

1/5 = (12/12)*(1/5) = 12/(5*12) = 12/60

and

1/12 = (5/5)*(1/12) = 5/(5*12) = 5/60

Then our previous sum:

1/5 + 1/12

can be written as:

12/60 + 5/60

and this is easy to solve:

12/60 + 5/60 = (12 + 5)/60 = 17/60

This is the fraction of the fish that are guppies or goldfish.
