Answer:
<em>x ≥ 2</em>
Step-by-step explanation:
Distribute 8:
8 (3.5x - 2) ≥ 40
28x - 16 ≥ 40
Add 16:
28x ≥ 40 + 16
28x ≥ 56
Divide by 28:
x ≥ 56 ÷ 28
x ≥ 2
x ≥ 28
1. 8(3.5x-2) ≥ 40
2. 28x - 16 ≥ 40
<u>+ 16 + 16</u>
3. x ≥ 28
45.1
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
I believe the answer is y=x+-13
