Youn could test all of the options by putting 8 and 3 in for a and b.

A.    a - b = 5
       8 - 3 = 5
            5 = 5

B.   a + b = 5
      8 + 3 = 5
            11 ≠ 5

C.   a - b = 8
      8 - 3 = 8
           5 ≠ 8

D.   a + b = 8
      8 + 3 = 8
            11 ≠ 8

As you can see, the only one that works is A. a - b = 5.

Dovator [93]

Answer:

30.1

Step-by-step explanation:

it is subtraction because it is asking how many more pounds of gravel does Ben use in his front yard than his back yard and his front yard has a bigger number so you subtract.

136.2-106.1= 30.1

Use the Pythagorean Theorem to find the length of the leg in the triangle shown below.
Natali [406]
The answer to what the length of the leg would be is 15.

You would do this problem by first writing down your Pythagorean Theorem, which is a^2 + b^2 = c^2.

Since we have our hypotenuse which is c^2 in our equation, we would write or insert the number we have.

So our equation could be that a or b leg equals 20, it doesn’t matter which one.

So we could write, 20^2 + b^2 = 25^2. So we don’t know what b leg is.

First we should figure out what 20^2 is and what 25^2 is.

20^2 is 400 and 25^2 is 625.

Our equation now comes to 400 + b^2 = 625.

Now we take 400 and subtract it from
625 -> 400 + b^2 = 625
-400.

So 625 - 400 comes out to be 225.

Lastly instead of squaring or putting 225 to the second power, we do the opposite.

So instead of squaring 225 we must square root 225. √ 225 .

The square root of √ 225 comes out to be 15.

PLEASE ANSWER THIS QUESTION! I BEG OF YOU
Law Incorporation [45]

The difference between the rate of change of B and the rate of change of A is 15.

<h3>How to get the difference in the rates of change?</h3>

First, we need to get the two rates of change.

We have two linear functions.

A: y = 35*x

For function A the rate of change is the slope, wich is 35.

Function B is graphed.

Remember that if a line passes through two points (x₁, y₁) and (x₂,y₂) then the slope is:

a = \frac{y_2 - y_1}{x_2 - x_1}

In the graph, we can see that line B passes through (0, 0) and (1, 50), then the slope is:

a = \frac{50 - 0}{1 - 0} = 50

Then the rate of change of B is 50.

The difference between the rates of change is:

diff = 50 - 35 = 15

A van travels 150 miles on 6 gallons of gas. How many gallons will it need to travel 325 miles?
shtirl [24]
<h3>Answer:  C) 13 gallons</h3>

============================================================

Work Shown:

(150 miles)/(6 gallons) = (325 miles)/(x gallons)

150/6 = 325/x

150*x = 6*325 .... see note below

150x = 1950

x = 1950/150 .... divide both sides by 150

x = 13 gallons is the final answer

-----------

Note: in this step, I cross multiplied. The general template for cross multiplication is that we go from A/B = C/D to A*D = B*C. As the name implies, the "cross" refers to the "X" shape that forms when you multiply the terms.
