Question

Any 8 numbers gor is 9 & s.D. Is 9.25 . The six numbers are 4, 6, 7, 10, 12, 13 , then what are the other 2 no.

Answer 1

Let x = the smaller number

Let x + 10 = the larger number

2x + 3(x+10) = 55 Use the distributive prop. to remove parentheses.

2x + 3x + 30 = 55 Collect like terms.

5x + 30 = 55 Subtract 30 from both sides.

5x = 25 Divide both sides by 5.

x = 5, the smaller number

x + 10 = 5 + 10 = 15, the larger number

Answer 2

X + 10 = 5 + 10 = 15 is the larger no.
