5 0

Answer:

Jiri's age is 25.

Step-by-step explanation:

Let P = Pamela's age

and J = Jiri's age. Then

(1) P = J - 12

(2) P + J = 38

Substitute (1) into (2) J - 12 + J = 38

Add 12 to each side J + J = 50

Combine like terms 2J = 50

Divide each side by 2 J = 25

Jiri's age is 25.

f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24

The answer is 5 because first, you make the expression 15/6*7-39 then simplify so that it becomes 15/42-39 simplify again to get 15/3 which equals 5
