Solve for x. 7(x+11)=9x-18

7(x+11)=9x-18

7x + 77 = 9x - 18

7x - 7x + 77 = 9x - 7x - 18

77 = 2x - 18

18 + 77 = 2x - 18 + 18

95 = 2x

95/2 = 2x/2

x = 47.5

Step-by-step explanation:

1. distribute the bracket

2. subtract 7 from both sides

3. add 18 to both sides

4. divide both sides by 2

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
