Answer:
x = 5
Step-by-step explanation:
im too tired to explain just trust me
(5) + 2 = 7
2(5) + 3 = 13
13 * 7 = 91
Answer: he got 80/100 or 80% right
Step-by-step explanation:
24/30 = 12/15
12/15 as a percent:
100/15 = 6.66666666666667
12 x 6.66666666667
15 x 6.66666666667
= 80/100 or 80%
Answer:
10
Step-by-step explanation:
5C2 =<u>5!</u>
2! (3)!
=<u>1 x 2 x 3 x 4 x 5</u>
(1 x 2) (1 x 2 x 3)
=<u>4 x 5</u>
2
=<u>20</u>

5C2 = 10
Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.
