Answer: x=10
Step-by-step explanation: 9 + 4x-12 + 6x = 97
Combine like terms: 6x + 4x and 9-12
10x -3 = 97
Add 3 to both sides
10x = 100
Divide 10 by both sides
X=10
Answer:
14 elliptical machines
Step-by-step explanation:
t = # of treadmills
e = # of elliptical machines
t + e = 38
t = e + 10
Substitute:
e + 10 + e = 38
2e = 28
e = 14
Answer:
147 degrees
Step-by-step explanation:
all the angles of a triangle add up to 180 degrees. so, you must perform the operation 180-(83+64) which equals 33. this is the angle supplementary to angle 1. to find angle 1, you must subtract 180 and 33 since supplementary angles add up to 180 degrees. this is equal to 147 degrees.
