Answer:
z ≥ 2
Step-by-step explanation:
Step 1: Write inequality
-7z - (-5z - 4) ≤ -3z - 2 + 4z
Step 2: Solve for <em>z</em>
- Distribute negative: -7z + 5z + 4 ≤ -3z - 2 + 4z
- Combine like terms: -2z + 4 ≤ z - 2
- Add 2z to both sides: 4 ≤ 3z - 2
- Add 2 to both sides: 6 ≤ 3z
- Divide both sides by 3: 2 ≤ z
- Rewrite: z ≥ 2
I’m thinking it’s $100. I guessed 100 first as that is a pretty common number and subtracted 61.75. I was left with 38.25 and I divided that by 3, the amount of washes. I got $12.75 but I had to check since I guessed 100. I then subtracted 23.50 from 100 and got 76.5. I divided that by 6, the amount of washes, and got 12.75 again. So I’m pretty sure that there was $100 on the gift card before he washes his car six times, each wash being $12.75.
Answer:
if you meant x times y...
15 x 20 is 300.
if you meant x + y...
15 + 20 is 35.
if you meant anything else, please let me know
the way it was written confused me but I tried.
