What equation does this set of algebra tiles represent? -x -x -x = -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 Combine like terms on each side of the equation. For example, write 3 instead of 1 + 1 + 1.

im not totally sure but i THINK MAYBE POSSIBLEY. its 1 just maybe

Step-by-step explanation:

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
