Simple...
remember A(B+C)=A*B+A*C
You have to have a common factor in both terms..(number)..this number would be 6.
So we know it has to have 6 in your answer.
If we plug n chug..:
20*6+20*5=220
6*40+6*5=270
6*40+6=246
6*4+6*5=54
6*45= 270
This being said, 6*40+6*5 is the choice you need.
Thus, your answer.
Answer:
20 miles per hour, or 20m(miles)/ per hour
Step-by-step explanation:
Whats 100÷5? Obviously 20, and fact check that by doing 20×5, 100. So it's 20 miles per hour, 0.3 (I think), per minute.

5x + -7 = -10x + 8
Reorder the terms:
-7 + 5x = -10x + 8
Reorder the terms:
-7 + 5x = 8 + -10x
Solving
-7 + 5x = 8 + -10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10x' to each side of the equation.
-7 + 5x + 10x = 8 + -10x + 10x
Combine like terms: 5x + 10x = 15x
-7 + 15x = 8 + -10x + 10x
Combine like terms: -10x + 10x = 0
-7 + 15x = 8 + 0
-7 + 15x = 8
Add '7' to each side of the equation.
-7 + 7 + 15x = 8 + 7
Combine like terms: -7 + 7 = 0
0 + 15x = 8 + 7
15x = 8 + 7
Combine like terms: 8 + 7 = 15
15x = 15
Divide each side by '15'.
x = 1
Simplifying
x = 1
