Answer:
x = 4
Step-by-step explanation:
Equation: 3x + 13 = 25
Step 1: Subtract 13 from both sides.
3x + 13 = 25
<u>- 13 - 13</u>
3x = 12
Step 2: Divide both sides by 3.
<u>3x</u> = <u>12</u>
3 = 3
x = 4
Please provide more information. You need to add the sides of the polygon to find the perimeter.

Answer: $130</h3>
=======================================================
Explanation:
I'm assuming the bank is using simple interest (instead of compound interest).
If so, then,
i = P*r*t
i = 8000*0.0325*0.5
i = 130
The amount of interest is $130
In the formula above, I used
- P = 8000 = amount deposited
- r = 0.0325 = annual interest rate in decimal form
- t = 6/12 = 0.5 years, which means you don't use t = 6. We don't use t = 6 because the interest rate is on an annual basis, and not a 6-month basis.
A) N + D = 30
B) .05N + .1D = 2.20
Multiplying equation A by -.05
A) -.05N -.05D = -1.50 then adding it to B
B) .05N + .1D = 2.20
.05D = .70
Dimes = 14
Nickels = 30 -14 = 16
