Plan a is 18 inches tall after one week 36 inches tall after two weeks 56 inches tall after three weeks plan b is 18 inches tall after one week 36 inches tall after two weeks 54 inches every three weeks which situation represents a proportional relationship between the plant height and number of weeks

Clarence wants to buy a new car. he finds an ad for a car that costs 27,200 dollars. suppose his local sales tax is 7%. -how much would he have to pay? -what is the cost of the car including tax? -if clarence has 29,864 saved, can he pay cash to buy the car?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.

In the diagram below, abc is congruent to dec what is the value of x
