Write the word sentence as an equation.

5 is one-fourth of a number c.

5=NxC divided by 1/4 ( don't have division sign on computer)

Step-by-step explanation:

First we now that it will start with 5=, because it says "5 is..." then we see that we have to multiply the number by c, sense it just says "...a number c" without an action so we assume its multiplication. Finally we divide NxC by 1/4 to fine one fourth of a number c, which equals five.

5=1/4 x c

If we have 5, that is 5= then 1/4, so 5=1/4... the of is multiplication so we have 5=1/4 x c.

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
