Show how to make ten to solve 13-7. Write in a number sentence. _-_-_-_-_=_

ser-zykov [4K]

Answer: The answer is 6.

The number sentence is

3-3=0

10-4=6

So, 13-7=6

Step-by-step explanation:

To solve $13-7$ , by making ten

First break 13 and write $13=10+3$

Then break 7 as $7=3+4$

Now to subtract 7 from 13,

Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4

$13-7=10+3-(3+4)=10+3-3-4=10-4$

Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.

The answer is 6.

Which ordered pair in the form (x, y) is a solution of this equation?

laiz [17]

Answer:

Substitute the x and y values from the ordered pairs into the equation, one by one, until both sides of the equation are equal.

Step-by-step explanation:

A. (-2,-3)

3 * (-2) - 4 * (-3) = 21

-6 + 12 = 21

6 = 21 not equal

B. (0,7)

3 * 0 - 4 * 7 = 21

0 - 28 = 21

- 28 = 21 not equal

C. (7,0)

3 * 7 - 4 * 0 = 21

21 - 0 = 21

21 = 21 equal
