Answer:
The percentage decrease is 15%.
Step-by-step explanation:
To find the percent decrease of any two numbers, subtract the numbers and divide it by the original.
So in this case:
20-17÷20
= 3÷20
= 0.15
Now convert to a percent.
0.15×100 = 15%

Step-by-step explanation:
<u>Step 1: Define</u>
12x - 30 = 2x - 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2x on both sides: 10x - 30 = -5
- Add 30 to both sides: 10x = 25
- Divide 10 on both sides: x = 5/2
