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!

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values
