Answer:
x = 4
Step-by-step explanation:
we know that 72 and (2x + 10) add up to 90
90-72 = 18
(2x + 10) = 18
2x = 8
x = 4
10 1/2 I am pretty sure its right
X = -10
Explanation:
-1.1x + 8.1x + 38 = -32
Combine like terms : -1.1x + 8.1x
7x + 38 = -32
Subtract 38
7x = -70
Divide by 7
7x = -70/7
Answer:
x = -10
the answer for the question is b! :)
Answer:x = 75
Step-by-step explanation:y=105 - 5 = 100 ft
z=125 ft
dz/dt=2 ft/sec
by using Pythagorean Theorem, we find x
x^2 + 100^2 = 125^2
x = 75
