Answer:
Step-by-step explanation:
The midline is half the length of the parallel base.
2(2x +36) = 3x +57
4x +72 = 3x +57 . . . . . . eliminate parentheses
x = -15 . . . . . . . . . . subtract 72+3x from both sides
Then the length of GH is ...
GH = 2x +36 = 2(-15) +36 = -30 +36
GH = 6
_____
The calculation steps are shown above. The strategy is to take advantage of the relation between the lengths of a midline and the corresponding base segment.

Below are explanations!
Step-by-step explanation:
6) 5^4/5^2 means the ^4 and ^2 needs to subtract from the 5s. This results in 5^2, which equals 25.
7) The 9 as the denominator will cross with the first nine above. This leaves as follows: 9^3 x 9^2 x 9^6 (I don't know if it is a 6 or 0). You may solve from there. Just add all the exponents up.
8)^-6 will be multiplied by ^6, which is ^-36. Therefore, the answer is 5^-36.
The other questions, please, remember to read carefully.
1. if we add something in x then it will also add up in value of y
2. x by 5 times then y value increases by 3*5 = 15 times
3. if x is added with 5 then y value increases by 8.
<h3>What is Algebra?</h3>
Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
As, per the first part
y=x
So, if we add something in x then it will also add up in value of x.
In second part,
y=3x
If x by 5 times then y value increases by 3*5 = 15 times
In third part, if x is added with 5 then y value increases by 8.

Answer:
1.6 ft
Step-by-step explanation:
Each time the wheel does a complete turn, the bike moves forward a distance equal to the wheel's circumference. Since the bike moves 200 ft after 40 rotations, the length of the wheel's circumference is:
C = 200 ft / 40
C = 5 ft
Circumference is π times the diameter. So the diameter of the wheel is:
C = πd
5 ft = πd
d = 1.6 ft
