Step-by-step explanation:
Deepak charges for each Job = $30
An additional charges for working each hour = $15
Let x be the number of hours he worked for each job.

So,he earns in total at each job =
We are also given that He only accepts jobs if he will earn at least $90 the job.
This means he must earn $90 or more than that .
So, the inequality becomes:
Hence an inequality to determine x, the number of hours he must work during each job in order to accomplish this is
Answer:
Step-by-step explanation:
We can set up the following system of equations:
, where
is the number of dimes she has and
is the number of nickels she has.
Multiplying the second equation by -5 and adding both equations lets us isolate and solve for :
Plugging into any of the two equations will let us solve for
:
.
Therefore, she has 14 nickels.
Answer:
11, 13,15 8, 11, 14 op = 2,3
16, 12, 8 17. 14, 11 op = -4,-3
3, 7, 15 24, 16. 12 op 4,4 because difference = op 4, 8 = 4 op -8, -4 = 4
Step-by-step explanation:
9+ 2 = 11, 13,15 ordered pair 2
5+ 3 = 8, 11, 14 ordered pair 3
20-4 = 16, 12, 8 ordered pair -4
20-3 = 17. 14, 11 ordered pair -3
1 x 2 +1 = 3, 7, 15 ordered pair 4, 8 = 4
40 / 2 + 4 = 24, 16. 12 ordered pair -8, -4 = 4
