Please help asap with this question!! :)

Step-by-step explanation:

3x + 9x +12 = 180 {linear pairr}

    12x + 12 =180

        12x = 180 - 12  

         12x = 168

             x = 168/12

x = 14

3x  = 3*14 = 42

4y - 10  + 3x = 180         {linear pair}

4y - 10 + 42 = 180

         4y + 32 =180

              4y  = 180 - 32

              4y = 148

                y = 148/4

               y = 37

x = 14, y = 37

Step-by-step explanation:

The angle vertically opposite (4y-10) is also a corresponding angle to (9x + 12) so that means that angles (4y-10) and (9x+12) are equal.

4y-10 = 9x+12 Equation 1

You also know that (4y-10) and 3x add up to 180° since they both lie on a straight line.

4y-10+3x = 180 Equation 2

From the above equation, I'm going to isolate (4y-10) so that I know a value that I can substitute in Equation 1.

4y-10 = 180-3x Equation 3

Substitute 4y-10 = 180-3x into Equation 1.

4y-10 = 9x+12

180-3x = 9x+12

Put the like terms together.

180-12 = 9x+3x

Evaluate.

12x = 168

Find x.

x = 168 ÷ 12

x = 14

Subsitite x = 14 into Equation 3.

4y-10 = 180-3x

         = 180-3(14)

         = 180-42

         = 138

Isolate 4y.

4y = 138+10

    = 148

Find y.

y = 148 ÷ 4

y = 37

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
