- 2.5(4w - 4) = -6 Check:

Step-by-step explanation:

- 2.5(4w - 4) = -6

-2.5×4w+2.5×4=-6

-10w+10=-6

-10w=-6-10

-10w=-16

Cancel the -sign from both side soqe get

10w=16

W=16/10

W=1.6

So the value of w is 1.6

-8

step-by-step explanation:

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
