(-2)³ = -8
-4⁴ = 256
= 125/216
= 1/4³ = 1/64 (every number with negative exponent is equivalent to the opposite of the number itself)
2-(-3)² = 2-(+9) = 2-9 = -7
-(-7)⁰ = -1 (every number elevated to 0 is 1)
1-3⁻¹ = 1-1/3 = 2/3
Answer:
x = 10.
Step-by-step explanation:
x + (-8) = 2.
First, isolate x by adding 8 to both sides.
x = 8 + 2.
Next, solve.
x = 10.
Finally, you can come to the conclusion that x = 10. Always plug in your answer to make sure it works.
10 - 8 = 2.
2 = 2.
(X +(x + 4) +3x)/3 = (5x +4)/3
Add the ages together and divide by the number of people to get the mean.
