Let n be the common factor for the ratio 6:5. Then:
6n+5n=330
11n=330
n=30
aerobics=6n=180 min
weight training=5n=150 min

-32=4(y-5)-7y <br> solve for y
Savatey [412]

Answer:

y= 4

Step-by-step explanation:

-32= 4(y -5) -7y

Expand:

-32= 4y -20 -7y

Simplify:

-32= -3y -20

+20 on both sides:

20 -32= -3y

Simplify:

-12= -3y

Divide both sides by -3:

y= -12 ÷(-3)

y= 4
