F is directly proportional to a . If F = 24 when a = 8 find, F when a = 6

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)

The algebraic expression shown below is missing two whole number constants. determine the constants so that the expression simplified to 14x + 11 4x + 8(x + + + 2x
