Answer:

x=-2

Step-by-step explanation:

-12x-2(x+9)=5(x+4)

-12x-2x-18=5x+20

-14x-5x=20+18

-19x=38

x=38/-19

x=-2

Answer:

C

Step-by-step explanation:

Given

- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides

- 12x - 2x - 18 = 5x + 20, that is

- 14x - 18 = 5x + 20 ( subtract 5x from both sides )

- 19x - 18 = 20 ( add 18 to both sides )

- 19x = 38 ( divide both sides by - 19 )

x = - 2 → C

Please help I need help with #17, 19, and 21
viktelen [127]

Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53
