Anil mean score in 4 tests is 65 he wants to increase his mean by 7 Mark's how many Mark's must he score in his 5th test

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

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

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
