Answer:
70percent =42
100percent ×42 ÷70
100/7×42
10/7×42=60
therefore the original cost was $60
Yes, all 6 digit numbers have 6 addends in their expansion
100-55=45%
45/100 × x = 423
x = (423)/(45/100)
x=940 peoples
He made 3.75 gallons. There was 1/10 remaining, meaning each tenth was 6 cups. The entire thing is 10 tenths so you do 6(10) to get 60 cups. After converting to gallons by doing 60÷26, you get 3.75.
Firstly make the f(x) = x and x = y:
x = y^2
Then solve for y:
√x = y
Hopefully this helps and let me know if you have more questions!
