xeze [42]

Answer:

D. $x-\frac{5}{2}y = \frac{25}{2}$

Step-by-step explanation:

Given

$y = \frac{2}{5}x - 5$

Required

Determine its equivalent

From the list of given options, the correct answer is

$x - \frac{5}{2}y = \frac{25}{2}$

This is shown as follows;

$y = \frac{2}{5}x - 5$

Multiply both sides by $\frac{5}{2}$

$\frac{5}{2} * y = \frac{5}{2} * (\frac{2}{5}x - 5)$

Open Bracket

$\frac{5}{2} * y = \frac{5}{2} * \frac{2}{5}x - \frac{5}{2} *5$

$\frac{5}{2}y = x - \frac{25}{2}$

Subtract x from both sides

$\frac{5}{2}y - x = x -x - \frac{25}{2}$

$\frac{5}{2}y - x = - \frac{25}{2}$

Multiply both sides by -1

$-1 * \frac{5}{2}y - x * -1 = - \frac{25}{2} * -1$

$-\frac{5}{2}y + x = \frac{25}{2}$

Reorder

$x-\frac{5}{2}y = \frac{25}{2}$

Hence, the correct option is D

$x-\frac{5}{2}y = \frac{25}{2}$

3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour

next, take 4.5 and divide by the new mph 12.5 from your previous answer.

4.5/12.5=0.36 hours

7 groups of 8=6 groups of 8 plus

vredina [299]

Answer:

7 groups of 8 = 6 groups of 8 plus 1 group of 8

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

7 groups of 8 = 6 groups of 8 plus ?

2. Let's answer the question, this way:

How much are 7 groups of 8? 56 = 7 * 8

How much are 6 groups of 8? 48 = 6 * 8

What is the difference between 7 groups of 8 and 6 groups of 8?

(7 - 6 ) * 8 = 1 * 8

Therefore,

7 groups of 8 = 6 groups of 8 plus 1 group of 8
