Solve the equation. You may find using algebra tiles helpful in solving this problem. x + 4 = −x − 4

x =
HELPPP MEHH PLZZZ

x = -4

Step-by-step explanation:

So we have this algebraic equation: x + 4 = −x − 4

All we have to do is move all the x's to the right hand side and the other numbers to the left hand side, like this:

x + x = - 4 - 4

2x = -8

x =

x = -4

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
