Answer:

a = 0

Step-by-step explanation:

given

-12 + 8a =-a + 6(2a -2)

Distribute the righ side

-12 + 8a = -a +6x2a -6x2

-12 + 8a = -a +12a - 12

-12 + 8a = 11a -12

Collect like terms

-12 + 12 = 11a - 8a

0 = 3a

Divide both sides by 3

0/3 = 3a/3

0 = a

a = 0

Answer:

41/6

Step-by-step explanation:

-12+81=-1+6(2a-2)

first distribute:

-12+81=-1+12a-12

combine like terms:

<u>-12+81</u>= <u>-1</u>+12a<u>-12</u>

69=-13+12a

add -13 with 69:

82=12a

divide 82 and 12:

82/12= 41/6

I need help with geometry!
ss7ja [257]

Step-by-step explanation:

If m is parallel to n and one of its angle is 25

Therefore, the vertically opposite angle to angle of 25 is also equal to 25

Now, we have to find x

Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)

Therefore, x =155
