Answer:
Part 1: 4.5
Part 2: 20%, 0.2
Step-by-step explanation:
1. 1.8 = 80% We need to understand this.
So we can do this then:
2. 1.8/8 = 80%/8
3. 0.225 = 1%
4. 0.225 * 20
5. 4.5
(this is part 1 btw)
<u>Part 2!</u>
20% since 100-80 is 20.
20% -> 0.2

Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}
You can use this to help you to find the answer
