<em><u>Question:</u></em>

If (x + 2)/2 = y /5, then which of the following must be true?

x/2 = (y-2)/5

x/2 = (y-5)/5

(x+2)/5 = y/25

<em><u>Answer:</u></em>

<em><u>The true is:</u></em>

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

<em><u>Solution:</u></em>

Given that,

\frac{x + 2}{2} = \frac{y}{5}

The above expression can be rewritten as:

\frac{x}{2} + \frac{2}{2} = \frac{y}{5}\\\\Simplify\\\\\frac{x}{2} + 1 = \frac{y}{5}

Move the constant 1 from left side of equation to right side of equation

\frac{x}{2} = \frac{y}{5} - 1

Simplify the right side of equation by making the denominator same

\frac{x}{2} = \frac{y}{5} - \frac{ 1 \times 5}{ 1 \times 5}\\\\\frac{x}{2} = \frac{y}{5} - \frac{  5}{  5}\\\\\frac{x}{2} = \frac{y - 5}{5}

Thus \frac{x}{2} = \frac{y - 5}{5} is true

tigry1 [53]

Answer:

19 hrs

Step-by-step explanation:

t varies inversely with number of people p

t = k/p

If it takes 7.125 hrs for 8 workers to do the job

K = tp

= 7. 125 x 8

= 57

How many hours will it take if there are 3 workers .

Recall t = k/p

t = 57/3

Two number have a sum of 71 and a difference of 37
larisa86 [58]
The right answer for the question that is being asked and shown above is that:

Two numbers have a sum of 71 and a difference of 37
x + y = 71
x - y = 37

So in order to get the two numbers, here it is:
x + y = 71
x - y = 37
------------
2x = 108
x = 54
y = 71 - 54
y = 17

<span>So the two numbers are 54 and 17</span>
