Answer: 25%
Step-by-step explanation:
We know that 20 divided by 5 is 4, so 5 is one-fourth of 20 or 25%.
Answer: x=11
Step-by-step explanation:
AB+BD=AD
(2x+8) + (4x+12) = 86
Combine like terms.
6x + 20 = 86
Minus 20 from both sides to get x by itself.
6x = 66
Divide both sides by x to find the value of a singular x.
x= 11
it is because when you have a negative exponent it goes backwards
- 10^-2
- you move backwards 2
