Answer:
d/dx ( 32x - 5)
Step-by-step explanation:
i think this is right please tell me if its not
<span>let the angles be x and y.
as they are compliment
x+y=90
also given
x=7y
substituting value of x in first equation
7y+y=90
8y=90
therefore
y=11.25
x=7*y=78.75</span>
The angles are complementary meaning they =90 degrees.
So take (x-20) and x, and write this equation,
x-20+x=90
2x-20=90
move the 20 over
2x-20=90
+20 +20
2x=110
x=55.
You can check it by plugging it back in,
(55-20)=35
and
x=55
35+55=90.
Thus, you know your answer is correct.
To figure out who is taller, we can take each mixed number and find a common denominator.
5/16 (x3) 15/48
7/24 (x2) 14/48
This tells us that Ben is taller because Marcus is shorter than him by 1/48.
