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
The measurements are in inches but the answer needs to be in feet, so we'll convert the numbers to feet first.
6"=1/2 ft
2"=1/6 ft
3"=1/4 ft
V=l×w×h
V=1/2*1/6*1/4
V=1/48 cubic ft

Answer:
$870
Step-by-step explanation:
To figure out how much the final value here is, use the formula A = P(1 + rt). (A = total accured amount, P = principal, r = rate (%), t = time (years))
A = 600 * (1 + (10 * 9/200)) (multiply 10 by 9 and put that over 200)
A = 600 * (1 + (90/200)) (90/200 simplifies to 9/20)
A = 600 * (1 + (9/20)) (add 1 (20/20) to 9/20 to get 29/20)
A = 600 * 29/20 (Multiply 600 by 29 and put that over 20)
A = 17400/20 (Divide 17400 by 20 to get 870)
A = 870
$870 is the final value.
