Answer:

212

Step-by-step explanation:

<u>Rule</u>

  • Subtract the 2nd number from the first to obtain the first digit(s) of the answer.
  • Add the 2nd number to the 1st to obtain the last digit(s) of the answer.

5 - 3 = 2

5 + 3 = 8

Therefore: 28

9 - 1 = 8

9 + 1 = 10

Therefore: 810

8 - 7 = 1

8 + 7 = 15

Therefore: 115

6 - 2 = 4

6 + 2 = 8

Therefore: 48

7 - 5 = 2

7 + 5 = 12

Therefore: 212

Answer:

212

Step-by-step explanation:

Simple addition and subtraction is to be used here.

<u>5, 3 = 28 </u>

5-3 = 2 , 5+3 = 8

<u>9 , 1 = 810</u>

9-1 = 8 , 9+1 = 10

<u>8 , 7 = 115</u>

8-7= 1 , 8+7 = 15

<u>6</u><u> </u><u>,</u><u> </u><u>2</u><u> </u><u> </u><u>=</u><u> </u><u>4</u><u>8</u>

6-2 = 4 , 6+2 = 8

<u>7</u><u> </u><u>,</u><u> </u><u>5</u><u> </u><u>=</u><u> </u><u>2</u><u>1</u><u>2</u>

7-5 = 2 , 7+5 = 12

Step-by-step explanation:

Jeremiah bought x toy sets for $20 each and then a video game for $60. Jeremiah spent a total of $220. How may toy sets did he buy?

To find our answer, we can solve the equation:

20x + 60 = 220

        -60    -60

20x = 160

/20    /20

x = 8

Jeremiah bought 8 toy sets!

I hope this helps :)
