Answer:
Step-by-step explanation:
carnival A : $ 6 dollar admission and $ 1.50 per ride
A(x) = 1.5x + 6
carnival B : $ 2.50 admission and $ 2 per ride
B(x) = 2x + 2.5
how many rides can Marnie go on so that the total cost of attending both is the same...
1.5x + 6 = 2x + 2.5
6 - 2.5 = 2x - 1.5x
3.5 = 0.5x
3.5 / 0.5 = x
7 = x <=== she would have to go on 7 rides for them to both cost the same
Answer:
8%
Step-by-step explanation:
3/4= 75%
75% + 17%= 92%
100% - 92% = 8%
The answer is actually 5.25 because i took the test and use the other users answer and it was wrong.
Step-by-step explanation:
2x + 1 = 16
2x = 15 (subtract 1 on both sides)
x = 7.5 (divide 2 om both sides)
Since 7.5 is not an integer, (a) is No.
However 7.5 is rational, therefore (b) is Yes.
