3(n - 5) = 24
Distributive property
3*n = 3n
3*5 = 15
3n - 15 = 24
+ 15 +15
3n = 39
3n/3 = 39/3
x = 39/3
x = 13
Answer: x = 13
Answer:
<u>31.85 square feet</u>
Step-by-step explanation:
Finding the radius :
- C = 2πr
- 20 = 2πr
- r = 20/2π
- r = 10/π
Substituting in the area formula :
- A = πr²
- A = π × 10/π x 10/π
- A = 100/π
- A = 100/3.14
- A = <u>31.85 square feet</u>
Its one, you get radical esquared which means ln e which is one if i remember correctly
Each bracelet should cost $8.50. Replace x with 8.50, 15(8.50)-28.50=99
