Answer:
d.) 2
Step-by-step explanation:
If you were going to solve the second part of the equation you would distribute and since we want the number we chose to equal 8, so the sides will be equivelent and their will be infinite solutions, we have to account for the *4 so if we do 8 ÷ 4 we will have the number we should use for infinite solutions
8÷4=2
You can also check it by putting 2 in the equation
4x + 8 = 4(x+2) now distribute the 4
4x+8=4x+8
The answer to c. Is 8t+12g
Answer:
x=50
Step-by-step explanation:
-0.2(x-20)=44-x
Distribute
-0.2x+4=44-x
Add x to each side
-.2x +4+x = 44-x+x
.8x+4 = 44
Subtract 4 from each side
.8x+4-4 = 44-4
.8x = 40
Divide each side by .8
.8x/.8 = 40/.8
x=50
Answer:
Step-by-step explanation:
Given:
Distribute to remove parentheses:
For simplification and clarity, reduce all mixed numbers to simplified common fractions:
Combine like terms:
Add 6/5 to both sides, then add 9/5x to both sides:
Divide both sides by -3/5 to isolate x (recall dividing by a number is equal to multiplying by its reciprocal):
