Answer:
Alex will need to work 4 hours.
Step-by-step explanation:
We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.
Answer:
I believe the answer is x< -141/7
−141
7
Step-by-step explanation:
Step 1: Subtract 15 from both sides.
−35x+15−15>720−15
−35x>705
Step 2: Divide both sides by -35.
−35x/-35> 705/-35
x < -141/7
Hope this helps! :)

Answer:
180
Step-by-step explanation:
10% of 300=30
30*6= 180 (to get 60 percent you multiply 10% by 6)
60%=180
Answer:
Step-by-step explanation:
Let the first term is a and common difference is d.
<u>The nth term is:</u>
<u>We have:</u>
<u>The difference of these terms is:</u>
- (a + 8d) - (a + 5d) = 16 - 15
- 3d = 1
- d = 1/3
<u>Then the first term is:</u>
- a + 5*1/3 = 15
- a = 15 - 5/3 = 13 1/3
<u>The nth term equation is:</u>
- aₙ = 13 1/3 + 1/3(n - 1) = 1/3n + 13
<u>If the nth term is 22, find n:</u>
- 1/3n + 13 = 22
- 1/3n = 22 - 13
- 1/3n = 9
- n = 9*3
- n = 27
