To find the value of x in the equation 9/4x + 2=20, you first get the term with x by itself on one side of the equation. how can you do that? what equation do you then have?

you put the variable to one side

Step-by-step explanation:

ex: 2x=5

Solve ex: 2x=5

x=5/2

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

a: 1/6, j: 1/4
