Answer:105
Step-by-step explanation:
first find f(7)
(7)^2 + 1
=50
then put the answer for f(7) in g of x
2(50) + 5
=105
70 adults and 100 children attended the carnival.
Step-by-step explanation:
Given,
Cost of each adult ticket = $10
Cost of each child ticket = $5
Total tickets sold = 170
Total revenue generated = $1200
Let,
Number of adults = x
Number of children = y
According to given statement;
x+y=170 Eqn 1
10x+5y=1200 Eqn 2
Multiplying Eqn 1 by 10

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 5

Putting y=100 in Eqn 1

70 adults and 100 children attended the carnival.

Answer:
777 fewer belts
Step-by-step explanation:
288/4 = 72
72 + 15 = 87
288*3 = 864
864 - 87 = 777
Since no equations were provided, the solution of the equation will depend on the values of p.
<h3>What is the solution of an equation?</h3>
The solution of an equation is the value that makes that equation true.
Given the equation q = 60 - 4p
The solution of the equation will depend on the value of p
For example; if p = 1
q = 60 - 4(1)
q = 56
Therefore, the solution of the equation will depend on the values of p.
