Hi there! Hopefully this helps!

<h2 /><h2>Answer: 235.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

First we need to <em>substitute the value of the variable</em> into the expression:

10a - 5b = 10(25) - 5(3).

Now we Multiply 10 and 25 to get <u>250</u>.

250 − 5 × 3 = 235

Multiply 5 and 3 to get <u>15</u>.

<u>250</u> − <u>15</u> = 235

<h2>Subtract 15 from 250 to get, you guessed it, 235!</h2>

Answer:

$\boxed{235}$

Step-by-step explanation:

<em>Hey there!</em>

Well given that,

a = 25

b = 3

10(25) - 5(3)

250 - 15

= 235

Calculate the slope of a line that passes through the points (-4,7) and (-1,3)

zmey [24]

Answer:

The answer is

$- \frac{4}{3} \\$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,7) and (-1,3)

We have

$m = \frac{3 - 7}{ - 1 - - 4} = \frac{ - 4}{ - 1 + 4} = - \frac{4}{3} \\$

We have the final answer as

$- \frac{4}{3} \\$

Hope this helps you

I added a screenshot of the question along with the given choices

<u><em>Answer:</em></u>
F. 4 <span>÷ 5

<u><em>Explanation:</em></u>
We know that Amy has 5 yards of boarders and that she will use them to make 4 equal borders.
<u>This means that:</u>
she will divide 5 yards by 4 to know the length of each border

Among the given choices, choices G, H and J show the division of 5 by 4 which is correct representation of the length
On the other hand. choice F shows the division of 4 by 5 which is an incorrect representation of the length.

Hope this helps :)</span>
