Answer:
Step-by-step explanation:
.45 * 120 = 54
.072 * 54 = 3.888
54 + 3.888 = 57.888= $57.89
A) 4*3 x 5*2
b) 9*4 x 7*2
c) 3 x 7*4
d) 2*2 x 9*4
8*5
Answer:
3.93 (approx.)
Step-by-step explanation:
3 ^ x + 6 = 3 ^ 4 can be rewritten as 3 ^ x = 3 ^ 4 - 6, or
3^x = 81 - 6 = 75.
Then 3^x = 75, or
x*ln 3 = ln 75
Solving for x:
x = (ln 75) / (ln 3) = 3.93 (approx.)
<u>Define x:</u>
Let the number of children tickets be x.
Children tickets = x
Adult tickets = 2x
<u>Construct the equation:</u>
4x + 7(2x) = 108
4x + 14x = 109
18x = 108
x = 6
x = 6
2x = 12
Answer: 6 children tickets and 12 adult tickets.
