In a recent survey 5 out of every 8 middle school students use a computer to complete school projects. franklin middle school has 520 students. how many are expected to use computers

You have to make a proportion:

needs to be set equal to  \frac{x}{520}[/tex] because it is equal to the 5:8 ratio

Then cross multiply to solve for x:

520 × 5 = 2,600

8 × x = 8x

^^^set those equal to each other and solve for x

2,600 = 8x

^^^to isolate x divide both sides by 8

(2,600 ÷ 8) = (8÷8)x

325 = (1)x

325 = x

325 students out of the 520 students that attend the middle school use computers

Hope this helped!

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
