Quiz - Level ) During a reading test, Enrique's younger sister reads a passage with 360 words. It takes her
4 minutes to read the passage.
How long would it take Enrique's sister to read a passage that has 720 words
if she reads at the same speed?

8 minutes.

Step-by-step explanation:

Set up a proportion: 360/4 = 720/x

Cross multiply: 720×4 = 2880 ; 360×x = 360x

Set up the equation: 360x = 2880

Divide 360 from both sides: x = 8

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
