Bought a set of 20 markers for 6 dollars how much would 1 market cost

$.30 cents

Step-by-step explanation:

Set up a ratio.

If 20 markers cost $6, 1 marker would cost ??

20/6 = 1/x

Cross multiply to solve.

20x = 6 so x=6/20 which is .30

3 dollars of cource use a calculator and dont waste points.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
