Answer:
n = 7
Step-by-step explanation:
You will want to add all common factors with each other.
So that would be n + 3n + 5n which would be 9n.
Then -8 + 1 would be -7. So now it should be 9n - 7.
You are going to set 56 equal to 9n - 7, so that would be 9n - 7 = 56.
After that, you will have to leave 9n alone by itself, so you would have to add 7 to both sides. Your final equation should be 9n = 63.
After that, you should divide both sides by 9 since you want n alone.
So 63 ÷ 9 would be 7. So at the end, <u>n = 7.</u>
Answer:
Step-by-step explanation:
- Estimated height is 4 feet
- Measured height is 4 feet 2 inches
1. The measurement is actual and should be considered as such. Estimate is approximate most of the time.
2. <u>The error is:</u>
- 4 feet 2 inches - 4 feet = 2 inches
3. <u>Percent error:</u>
- 2 inches/4 feet 2 inches × 100% =
- 2 inches / 50 inches × 100% =
- 0.04× 100% =
- 4%
Answer:
5
Step-by-step explanation:
The answer is 28
30 minutes is half of an hour so you have to divide 7 by 2 which is 3.5 and then multiply 3.5 by 8 to get 28
Answer:
t3 = 8, t5 = 14
Step-by-step explanation:
t3 = 2 + (3-1) × 3
t3 = 2 + (2) × 3
t3 = 2 + 6
t3 = 8
t5 = 2 + (5-1) × 3
t5 = 2 + (4) × 3
t5 = 2 + 12
t5 = 14
