Answer:
4w = 8
Step-by-step explanation:
Product is multiply
Is means equals
4w = 8
x+(-2) >3
open the bracket
x-2>3
collect the like terms by taking 2 to the other side
x>3+2
x>6
Hello,
If 1/3 of 480 students have traveled overseas, that means (1/3)(480) = 160 students have traveled overseas.
If 15% of the 160 students have been to Australia, then 1 - (0.15) = 0.85 = 85% of the 160 students have not been to Australia.
85% of 160 students = (0.85)(160) = 136 students have not been to Australia.
136 students have not been to Australia.
Hope this helps!
Answer:
66 gallons
Step-by-step explanation:
Given that initially 160 gallons of a solution containing 12% salt.
So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.
Let x gallons of water get evaporated so that the remaining solution contains 20% salt.
The remaining amount of solution = 160-x gallons.
As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so
19.2 = 20% of (160-x)
gallons
Hence, 66 gallons of water must be evaporated to get a 20% salt solution.
