4(3s) + 2(-t)

if s = 1/2 and t = -3, what would the answer be?

The expression would be = to 0.

Step-by-step explanation:

Starting with -4(3s) + 2(-t), substitute (1/2) for s and (-3) for t:

                    -4(3/2) + 2(+3)

This gives us:

                       -12/2 + 6 = 0              

the answer is n

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
