how many gallons of a 50 antifreeze solution must be mixed with 90 gallons of 20% antifreeze to get a mixture that is 40% antifreeze ?

what statement? is there an image?

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
