Answer:
Step-by-step explanation:
I think the below is your full question:
<em>Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20 hours per week. Graph two inequalities that Kishi can use to determine how many hours he needs to work at each job if she wants to earn at least $90 per week.</em>
Here is my answer:
Let x is the number of hours he works at the grocery store
Let y is the number of hours he works at the newspapers
We have two inequalities:
1/ x + y 
<=> y 
20 - x
2/ 7x + 10y 
<=> y 
3/4x + 12.5
Please look at the attached photo
The red line is y 20 - x
The blue line is: y 3/4x + 12.5

The answer is C. 9.946025 is the answer, but it's rounded up to 9.95.
Line plots are used to represent data using lines and dots
The difference between the greatest amount of water and the least is 1/2
From the line plot (see attachment), we have the following parameters:
<h3>Calculating the difference</h3>
The difference (d) is then calculated as:
So, we have:
Subtract the common terms (8)
Take LCM
Reduce the fraction
Hence, the difference between the greatest amount of water and the least is 1/2

Answer:
x = y/9 - 7/9
Step-by-step explanation:
Solve for x:
4 y - 36 x = 28
Subtract 4 y from both sides:
-36 x = 28 - 4 y
Divide both sides by -36:
Answer: x = y/9 - 7/9
