Answer:
2640 feet
Step-by-step explanation:
Let's make a proportion using this:
feet/seconds=feet/seconds
We know the car travels 88 feet in 2 seconds.
88/2=feet/seconds
We don't know how many feet the car can travel in 1 minute (which is equal to 60 seconds).So, the car travels x feet in 60 seconds.
88/2=x/60
We want to solve for x. To do this, we have to get x by itself. x is being divided by 60. Multiply both sides by 60, because multiplication is the opposite of division.
60*88/2=x/60*60
The 60s on the right will cancel, so we are left with
60*88/2=x
60*44=x
2640=x
The car can travel 2640 feet in 1 minute.
Answer:

Answer: C. X + 44
Step-by-step explanation:
Let x be the unknown number.
Given statement : "44 more than an unknown number".
By using addition operation ,
Mathematical expression for "44 more than an unknown number" = 44 +x
Hence, the correct expression is x+44.
So, the correct option is C.

Step-by-step explanation:
Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15
