Answer:
The area of the swimming pool is 2,847.45ft, assuming this pool is a rectangle.
Step-by-step explanation:
A=l*w
A=23.15*123
A=2847.45ft
Difference of squares makes (x+3)(x-3)/(x+3)
The x+3’s cancel out
Answer is x-3
divide the original price by 2 since it is half off. that gives you 6.44. so you would multiply 6.44 by 5, since allison wants 5 cases. that gives you 32.20 dollars
Answer:
63
Step-by-step explanation:
Set up the proportion
(6x+3)/17 = (8x - 1)/21 Cross Multiply
21 * (6x + 3) = 17 (8x - 1) Remove the brackets
126x + 63 = 136x - 17 Subtract 126x from both sides
63 = 136x - 126x - 17 Combine
63 = 10x - 17 Add 17 to both sides
63 + 17 = 10x Combine the left
80 = 10 x Divide by 10
80/10 = x
x = 8
Now you want 8x - 1
8*8 - 1 = 63
