The answer is b cause none of x is the same number
X=3
you can combine like terms to get -16x= -48 and then divide -48 by -16 to get 3
X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)
x^2 + y^2 -(4x27) = x^2 + y^2 -108
Answer:
e t
Step-by-step explanation:
9) 35% of the 12,000 are 50-64 years old.
12,000 x 0.35 = 4,200
