Answer:
3x +2=14
subtract 2 from both sides
3x + 2-2=14-2
3x=12
Step 2:Divide both sides by 3.
3x/3 = 12/3
x = 4
Step-by-step explanation:
Answer: 37
Step-by-step explanation:
I guessed on the quiz and got it right
Solving the expression
we get 25
Step-by-step explanation:
We need to rewrite the expression
without exponents
Solving:
![\frac{5^{-2}5^3}{5^{-1}}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5E%7B-2%7D5%5E3%7D%7B5%5E%7B-1%7D%7D)
Using exponent rule: ![a^{-1}=\frac{1}{a}](https://tex.z-dn.net/?f=a%5E%7B-1%7D%3D%5Cfrac%7B1%7D%7Ba%7D)
![=\frac{5^3}{5^{-1+2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%5E3%7D%7B5%5E%7B-1%2B2%7D%7D)
![=\frac{5^3}{5^{+1}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%5E3%7D%7B5%5E%7B%2B1%7D%7D)
![=\frac{125}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B125%7D%7B5%7D)
![=25](https://tex.z-dn.net/?f=%3D25)
So Solving the expression
we get 25
