Brian is going clothes shopping. he buys one t-shirt for $10 and “x” amount of shorts for $5 each, in total he spent $30. solve for “x”

what’s the question?

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
