Step-by-step explanation:
We can rewrite 7 as 3+4 then instead of 3*7 we have 3*(3+4).
Then distribute the 3 in the parenthesis 3*(3+4) = (3*3) + (3*4)
Step-by-step explanation:
8. 1/2 9. 50% or 1/2
Answer:
x = 112
Step-by-step explanation:
We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:
20*x + 5*y = 1200
x + y = 120
Then we can solve for x
x = 120 - y
then we can plug that into the top equation:
20(120 - y) + 5y = 1200
divide by 5:
4(120 - y) + y = 240
distribute:
480 - 4y + y = 240
and then do all that combining like factors what not and simplify and solve:
480 - 3y = 240
-3y = -240
y = 8
NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X
8+x =120
x = 112
