Hi there!
Answer:
-14.98%(or -15%).
Step-by-step explanation:
1)To find the percent decrease,all you have to do is minus the original number from the decreased amount so:
1435-1220= 215
2)Then you divide this answer by the original number again so:
215÷1435= 0.1498
3)Then you times the decimal by 100 so:
0.1489x100= -14.98%(or -15%).

Step-by-step explanation:
<u>Step 1: Define</u>
-2(5x - 5.5) + 8 = -9x + 2 - (-5)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: -10x + 11 + 8 = -9x + 2 + 5
- Combine like terms: -10x + 19 = -9x + 7
- Add 10x to both sides: 19 = x + 7
- Subtract 7 on both sides: 12 = x
- Rewrite: x = 12
