Simplif 1/2t to t/2
t/2 + 8 = 5/2t - 10
Simplify 5/2t to 5t/2
t/2 + 8 = 5t/2 - 10
Multiply both sides by 2
t + 16 = 5t - 20
Subtract t from both sides
16 = 5t - 20 - t
Simplify 5t - 20 - t to 4t - 20
16 = 4t - 20
Add 20 to both sides
16 + 20 = 4t
Simplify 16 + 20 to 36
36 = 4t
Divide both sides by 4
36/4 = t
Simplify 36/4 to 9
9 = t
Switch sides
<u>t = 9</u>
Answer:
110
Step-by-step explanation:
22/4=5.5
5.5*20=110
Put the given numbers in the appropriate formula and evaluate.
A = P(1 +r/n)^(nt)
P is the principal amount
r is the annual rate
n is the number of times per year interest is compounded
t is the number of years
A is the balance in the account after t years
a. A = $6000*(1 + .045/12)^(12*17) ≈ $12,875.53
b. A = $6000*(1 + .045/4)^(4*17) = $12,839.01
