What is the value of x in the equation 4 x plus 8 y equals 40, when y equals 0.8?

now first of all we should plug in 0.8 to y .

now we have this simple equation: 4x+8.(0.8)=40

4x+6.4=40

4x=33.6

x=8.4  (hope it helps :) )

Step-by-step explanation:

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
