Create equal fractions to find the number of hours he used the health club for.
2/13=x/29.25
Then, simplify so that x is by itself.
(29.25x2)/13 = x
x= 58.5/13
x=4.5 hours
Answer: False.
Step-by-step explanation:
This says;
If we have an interval I, f(x) is increasing if, for any two x1, x2 such that:
x1 ∈ I and x2 ∈ I.
where x2 > x1, ----> f(x1) > f(x2).
An increasing function means that, if the value of x increases, also does the value of f(x).
Particularly, here we have that x2 > x1
so x can increase from x1 to x2.
But we have that f(x1) > f(x2)
So here we can see that the actual value of f(x) decreases as x increases.
Then this is not a increasing function, so the statement is false.
Answer:
The cost for a child is $7 and the cost for an adult is $50
Step-by-step explanation:
Let 'x' represent children
Let 'y' represent adults
The equations used to come to this answer are:


Therefore; x = 7

Answer:
x = 14
Step-by-step explanation:
1/2 ( 4x - 6 ) = 21
2x - 3 = 21
2x = 24
x = 14
