7-7+16x-12x-6+x=12x-13x-12

x = -1

Step-by-step explanation:

7 - 7 + 16x - 12x - 6 + x = 12x - 13x - 12

Combine like terms

−6 + 5x = -x - 12

Add x to both sides

6x -6 = -12

Add -6 to both sides

6x = -6

Divide 6 to both sides

6x/6 = -6/6

x = -1

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
