c: 8
Step-by-step explanation:
<em>Explanation for a: Making the equations</em>
Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations since the total cost will be 800$, and we have a total of 13 ads.
<em>Explanation for b: Solving for h</em>
We can now solve for one of the variables using elimination. Let’s multiply the expression by -75.
Great! Now let’s add the equations.
Adding these equations, we get
Divide both sides by -35, and we get .
<em>Explanation for c: Solving for f</em>
We can now substitute h inside the equation .
Hope this helped!
Answer:
C. 25m
Step-by-step explanation:
7x - 5y = -140
Solve for y.
7x + 140 = 5y
5y = 7x + 140
y = (7/5)x + 28
To plot the line, draw a point at (0, 28).
Then go up 7 units and right 5 units and draw a point there.
Connect the two points with a segment and extend it in both directions.
