A restaurant used 6.5 ounces of cheese to make 5 slices of pizza. If each slice had the same amount of cheese, how much cheese was on each slice?

To find the amount of cheese on each slice, divide the total amount of cheese used by the number of slices: 6.5 ounces / 5 slices = <<6.5/5=1.3>>1.3 ounces/slice.

Each slice of pizza had 1.3 ounces of cheese. Answer: \boxed{1.3}.

The total price for 7 movie tickets is $79.10. If each ticket costs the same amount, how much does one movie ticket cost?

To find the cost of one movie ticket, divide the total price by the number of tickets: $79.10 / 7 tickets = $<<79.10/7=11.30>>11.30 per ticket.

Each movie ticket costs $11.30. Answer: \boxed{11.30}.

Plot the solution of the equation on the number line.

4 + x = -8

To solve the equation 4 + x = -8, we need to isolate x.

Subtract 4 from both sides of the equation:
4 + x - 4 = -8 - 4
x = -12

The solution to the equation is x = -12.

On the number line, we can plot -12 as a point:
--------------------------------------------------------------
-12

what would that look like on a number line?

On a number line, the point -12 would be plotted as a dot (-12) at the position corresponding to -12.

Here is what it would look like:

-12

Plot the solution of the equation on the number line.

-4 + v = 7

To solve the equation -4 + v = 7, we need to isolate v.

Add 4 to both sides of the equation:
-4 + 4 + v = 7 + 4
v = 11

The solution to the equation is v = 11.

On the number line, we can plot 11 as a point:
