calories a week. He finds that biking uses about 425 calories each hour and hip-hop
dancing uses about 325 calories each hour. He wants to do bike riding for x hours and
hip-hop dancing for y hours each week.

step-by-step explanation:

this is false ^.^ lol

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
