x = 81 degrees (The sum of a triangle's angles must be 180 degrees. 48 + 51 = 99, and 180 - 99 = 81)

y = 99 degrees (Y and X are on a supplementary angle. Like a triangle, a supplementary angle's angles must add up to 180 degrees. 180 - 81 = 99)

z = 129 degrees (Z and the 51 degree angle are also on a vertical angle. 180 - 51 = 129)

Hope this helps!

3(9-8x-4x)+8(3x+4)=11
Papessa [141]
3(9 - 8x - 4x) + 8(3x + 4) = 11

3(9 - 12x) + 8(3x + 4) = 11

27 - 36x + 24x + 32 = 11

59 - 12x = 11

-12x = 11 - 59 

-12x = -48

x = 4

hope this helps, God bless!

Help meeeeee with this! No links!
Gelneren [198K]

Answer:

There is a mistake in Step 2. Maya distributed 3(x-10) as 3x+30, which is false. The correct step is: 6x+12 = 3x-30

Then solve for x

The answer is B. Maya made a mistake between Step 1 and Step 2 because she did not correctly distribute 3  to (x-10).
