Two numbers have a sum of 15 and one
is of the other. find the numbers.

9 and 6

Let x be the larger of the two numbers. The other number is 15 - x, so

x - (15 - x) = 3

x - 15 + x = 3

2x - 15 = 3

2n = 18

x = 9

Then subtract 9 from 15 to get your other number.

m∠a is 90°

m∠b is 40°

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
