6 cupcakes ----1/3 sugar, 2 1/2 dozen = 2*12+12/2=24+6=30
30 cupcakes ---x
x=(30*1/3)/6=10/6=1 4/6=1 2/3 cups of sugar
(x-9)^2=7
“twice the difference of a number” would mean x-9 twice equals 7
Answer:
x + 2/5 = 4
subtract 2/5 from both sides
That is
x + 2/5 - 2/5 = 4 - 2/5
x = 4 - 2/5
x = 18/5 or 3 3/5 as a mixed number
