Emily chooses two numbers. She adds the two numbers together and divides the result by 2.
Her answer is 44. One of Emily's numbers is 12. What is Emily's other number?

Sagot :

(x+y)/2= 44

let x- 12

(12+y)/2= 44

12+y = 44*2

12+y= 88

y= 88-12

y= 76
apologiabiology
easiest way is algebra so
x+y are 2 numbers
if (x+y)/2=44
and x or y=12 (pic one)
so if x=12
subsitute
(12+y)/2=44
multiply both sdies by 2 to clear fraction
12+y=88
subtract 12 from both sides
y=76

the numbers are 12 and 76
