If it takes 3/7 of an hour to paint 3/5 of a room how long would it take to paint one room

x=5/7

Step-by-step explanation:

suppose x is room

3/5x=3/7 (multiply both sides by 5)

3x=15/7 (divide both sides by )

x=15/7 /3

x=5/7

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
