Answer:
w > -14
Step-by-step explanation:
Divide both sides by -6.
-6w/-6 = w
84/-6 = 14
Since it's an equality, if the coefficient of the variable is negative, when you divide the sign flips to the opposite.
Answer:
8
Step-by-step explanation:
Plug in 3 for x and simplify
2(3)^2 - 10
18-10
=8
She used 1221 wrapping paper for 21 gifts, so to find the individual amount, you would do:
1221/21
She used about 58.143 ft² of wrapping paper for each gift.
X=3
Divide both sides of the equation by 2
X^3 =27
Write the number in exponential form with an exponent of 3
X^3=3^3
Since the exponents are the same, set the bases equal
X=3
