If 4r = -24, what is the value of 6r + 3?

-33

Step-by-step explanation: First, let‘s solve for r. (4 x -6) = -24; so this means that r= -6. Next, let’s solve for r again, knowing that r = -6. (6 x -6) + 3 = ? Lastly, you should end up with an answer of -33.

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
