Answers

Answer: "Three times the sum of 8 and 4":3* (8+4)

Explanation:

In the question we have asked that what will be the mathematical expression for the " three times the sum of 8 and 4".

We have asked with 'Three times the sum of 8 and 4' which means that adding the sum of number '8' and number '4' by three times.

We can write 'Three times the sum' mathematically as '3 * (\text{sum of numbers})'.

We can write 'sum of 8 and 4' mathematically as '8+4

So the final expression comes out to be: 3*(8+4)
3(8+4) is your expression

Brine is a solution of salt and water. If a tub contains 50 gallons of a 5% solution of brine, how much water must evaporate to change it to an 8% solution?

Answers

Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 x = 18.75 lb of water evaporated : ; Check; amt of salt remains the same, only the percentage is different, right? .05(50) = .08(50-18.75) .05(50) = .08(31.25) 2.5 = 2.5
