Which number should each side of the equation 3/4x=9 be multiplied by to produce the equivalent equation of x = 12?

−34

1/4

4/3

4

1/4

Step-by-step explanation:

1/4 of 9 is 3, so 9 * 1/4 equals 12. 3/4 * 1/4 = 1, so x stays the same.

3/4x=9

*1/4

x = 12

828. all there is to it!

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
