Answer: A
Step-by-step explanation:
In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.

Answer:
16+x²
Step-by-step explanation:
Answer:
x=16
Step-by-step explanation:
we know that 3x+2=50 according to complemntary angles.
3x=48
x=16
Answer:
x =
Step-by-step explanation:
(x + 6 )^2 = 49
get rid of the square , by square rooting the 49
x + 6 =
x = -6
x =
means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1
therefore the answer is = or - 1
hence in terms of roots .. answer is :
