Step-by-step explanation:
Isolate the w. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, multiply 4/3 to both sides
(3/4)(4/3)(8w - 12) = 3(4/3)
8w - 12 = (12/3)
8w - 12 = 4
Isolate the w. Add 12 to both sides
8w -12 (+12) = 4 (+12)
8w = 4 + 12
8w = 16
Finally, to completely isolate the w, divide 8 from both sides
8w/8 = 16/8
w = 16/8
w = 2
2 is your answer for w

you need the top and bottom side lengths, we can call them a and b, you also need the height.
once you have those, plug it into the formula:
*h
Answer:
On her 60th birthday, she would have earned $83048.5.
Step-by-step explanation:
The formula to calculate the compound interest is:
--- (1)
where A is Principal and interest, r is the rate of interest and n is the number of years compounded.
For our problem,
P = 25000,
r = 0.05 and
n = 60 - 30 = 30
Substitute these values in (1), we get,
= 25000(4.32194)
= 108048.5
Compound Interest = Amount - Principal
= 108048.5 - 25000
= 83048.50
Hence, on her 60th birthday, she would have earned $83048.5.
