Ne4ueva [31]

Answer:

  • premium: 165 gallons
  • water: 120 gallons

Step-by-step explanation:

Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:

  0.95a +0(285 -a) = 0.55(285)

  a = 0.55/0.95(285) = 165 . . . gallons of 95%

  285 -a = 285 -165 = 120 . . . . gallons of water

There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.

A problem states: "There are 5 more girls than boys at the party. There are 27 children at the party in all. How many boys are t
Sever21 [200]
As there is 5 more girls than boys and b is the number of boys, the expression b + 5 represents the number of girls. 
total there are 27 childrens
b + (b+5) = 27
b + b + 5 = 27
2b = 27 -5 
b =22 / 2
b =11
so the number of boys there are 11 and girls are 11 + 5 = 16 
and total is 16 + 11 = 27

8 less than four times a number is 12 determine the number
blondinia [14]

Answer:

5

Step-by-step explanation:

With this one, you need to work backwards.

First, you want to add 8 to 12, as addition is opposite subtraction. This gives you 20. Then, you want to divide 20 by 4, as division is the opposite of multiplication. That gives you 5, which is your answer.

It works the other way round if you were to check it. 5 x 4 is 20, 20 - 8 is 12.
