Answer:
The equation that represents the money he spent by the time he was on the trampoline is "total amount = 7 + 1.25*x" and on that day he spent 29 minutes on the trampoline.
Step-by-step explanation:
The question is incomplete, but we can assume that the problems wants us to determine an equation for the time in minutes that Raymond spent on the Super Bounce.
In order to write this equation we will attribute a variable to the amount of time Raymond spent on the trampoline, this will be called "x". There were two kinds of fees to ride the trampoline, the first one was a fixed fee of $7 while the second one was a variable fee of $ 1.25 per minnute spent playing. So we have:
total amount = 7 + 1.25*x
Since he spent a total of $43.25 on that day we have:
1.25*x + 7 = 43.25
1.25*x = 43.25 - 7
1.25*x = 36.25
x = 36.25/1.25 = 29 minutes
The equation that represents the money he spent by the time he was on the trampoline is "total amount = 7 + 1.25*x" and on that day he spent 29 minutes on the trampoline.
The -1 affects the coefficient of the entire term.
Without the -1,
the term has a positive coefficient.
(3a)² = 9a²
However, with the -1,
the term has a negative coefficient.
-(3a)² = -9a²
Answer:
30
Step-by-step explanation:
You take a protractor and put at c then you measure
The answer is 30.
She spent $400 after the discount witch means the original total was $450, 450/15 = 30
