<h3>Answer: 33</h3>
=====================================
Work Shown:
8^(x+7) = 32^(x-9)
(8)^(x+7) = (32)^(x-9)
(2^3)^(x+7) = (32)^(x-9) .... replace 8 with 2^3
(2^3)^(x+7) = (2^5)^(x-9) .... replace 32 with 2^5
2^(3(x+7)) = 2^(5(x-9)) ... multiply exponents
3(x+7) = 5(x-9) ...bases are the same, exponents are the same
3x+21 = 5x-45
21+45 = 5x-3x
66 = 2x
2x = 66
x = 66/2
x = 33

Step-by-step explanation:
Answer:
$7.7
Step-by-step explanation:
Step one:
given data
total money = $175
He buys 4 shirts for $24 each= 24*4= $96
The shirts are discounted 20%
= 96- 0.2*96= 96-19.2= $76.8
2 pairs of shorts for $18 each= $36
2 pairs of pants for $22.50 each= $45
Total cost = $157.8
tax= 6%
total expenses
= 157.8+ 0.06*157.8
=157.8+9.468
=$167.268
The balance is
= 175-167.268
=$7.7
