Answer:
for both of the them the range geografeclly is 1 up
3x+18+9x - 27 = 99
12x - 9 = 99
12x = 108
x = 9
m<PSQ = 3x + 18
m<PSQ = 3(9) + 18
m<PSQ = 27 + 18
m<PSQ = 45
answer
C. 45
Smith's balloon is an algebraic expression
The expression that represents how many Balloons Smith has is p + 20

Answer:
The original price was $43.50
Step-by-step explanation:
Let
x ----> the original price of a video game
we know that
1) The price of a video game increases by 20%
so
The final price is equal to the original price multiplied by 1.20
so
2) The price of a video game decreases by 10%
so
The final price is equal to the price at this moment multiplied by 0.90
so
we have that
solve for x
The correct answer is answer A or x=29/2 or x=-15/2.
