Evaluate: 42 − 12 ÷ 6
—————————————————
(6 − 3) × 4 − 7

Answers

Answer:

42 - 12 ÷ 6 = 40

(6 - 3) x 4 - 7 = 5

Step-by-step explanation:

First of all, when coming over to an equation with a division or multiplication sign, we first solve the division or multiplication first, then the subtraction or addition. So, 12 ÷ 6 = 2. Then, 42 - 2 = 40. And in the other one we must first solve what's in the parenthesis. So, 6 - 3 = 3. Then, we multiply, 3 x 4 = 12. Then subtract. 12 - 7 = 5.

Hope this helps :)

Hello!

Inequality: [tex]-1.2z-8.2 > -9.7[/tex]

To solve, we need to add 8.2 to both sides of the inequality:

[tex]-1.2z-8.2+8.2 > -9.7+8.2\\-1.2z > -1.5[/tex]

Now to get our solution, we will need to divide both sides by -1.2:

[tex]\frac{-1.2z}{-1.2} > \frac{-1.5}{-1.2}\\[/tex]

Final answer:

[tex]\fbox{z} < \fbox{1.25}[/tex]

It is away from the hive for a total of 19 minutes. A. what equation can you use to find the distance of the flowerbed from the hive? B. How far is the flowerbed from the hive? Let d be the distance of the flowerbed from the hive.

Answers

Answer:

5 minutes

Step-by-step explanation:

d / r = t

The bee is flying for 19 - 14 minutes

(d / 6) + d / 4) = 5

Answer: 25 feet

Step-by-step explanation:

19 - 14 = 5

total travel time = 5 min

av. between 6 and 4

= 6+4÷2 = 5

5 feet per sec × 5 min = 25 feet

A lizard can lose its tail to escape a predator, and the tail will grow back at a constant rate. After 6 weeks, a lizard's tail has regrown to 3 3/4 inches long. Find the number of inches the tail grew each week.

Answers

Answer:

15/24 or 5/8 inches each week

Explanation and Checking part below :)

Step-by-step explanation:

3 3/4 ÷ 6

1. Turn the mixed number into an improper fraction.

15/4 ÷ 6/1

2. Use the KCF (keep,change,flip) method (multiply the reciprocal).

15/4 × 1/6 = 15/24

3. Simplify if needed to.

15/24 ----> simplified is 5/8

Check:

5/8 × 6 = 30/8

30/8 = 3 6/8 -----> Simplified to 3 3/4

You need to divide 3 3/4 into 6 which equals to 5/8 or 0.625
Explanation
3 3/4= (4* 3)+3= 15 and you add 4 on the bottom= 15/4 then divide into 6= 6/1 so we use kcf 15/4 * 1/6= 15/24 then simplify 15/25 divide into 3/3 equal 5/8

Answers

Answer: 20c + 10.

Step-by-step explanation:

(c represents crates)

I wrote each equation separately first.

Supplier A: 4c + 6

Supplier B: 6c - 1

Supplier C: 10c + 5

We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )

I got the answer 20c+10

4c+6 for supplier A
6c-1 for supplier B
10c+5 for supplier C

Combining the like terms of C you would get 20c
Then combining the other number (-1,6,5) you get 10

Answers

N * 4 =f
We know there are 4 times as many non-fiction books as there are fiction books so we would have to multiply non-fiction by 4 to figure out how many fiction books there are

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

We have,

Let's write a rule for the relationship between the number of non-fiction books (n) and the number of fiction books (f) based on the given information.

We are told that the library loans 4 times as many non-fiction books as it does fiction books.

This means that the number of non-fiction books (n) is equal to 4 times the number of fiction books (f).

Mathematically, we can express this relationship as:

n = 4f

Where:

n = Number of non-fiction books

f = Number of fiction books

Thus,

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

Which of the following points best represents the location of -1 5/8 on the number line?

Answers

Answer:

Step-by-step explanation:

Looking at the number line, you will notice that A, B, and C are less than 0.

Eliminate D, which is greater than 0.

Further still, as negative numbers get 'smaller', they go from -1 to -∞.

i.e.: -1 > -2 > -3

if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.

Write an equation with a slope: -3/4 and y-intercept: -1/4

Answers

Answer:

y = (-3/4)x - 1/4

Step-by-step explanation:

Use the slope-intercept formula y = mx + b. Here m = -3/4 and b = -1/4, and so: y = (-3/4)x - 1/4

The equation of the line with slope -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.

What is slope intercept form of line?

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

It describes the steepness of line in the coordinate plane.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that the slope is -3/4 and y-intercept is -1/4.

We have to find the equation of line with slope -3/4 and y-intercept is -1/4.

m=-3/4 and b = -1/4

Now plug in these values in slope intercept form y=mx+b

y=-3/4x-1/4

Hence, y=-3/4x-1/4 is the equation of the line with slope -3/4 and y-intercept is -1/4.
