Find the sum using the number line.10+( -5) Move the point on the number line as needed to choose the correct value for the sum?

Start at positive 10.

When adding a negative number move that many places to the left, so from positive 10 move 5 places to the left to get the answer which is positive 5

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00
