Answer:

12x-6

Step-by-step explanation:

For our first step, let's rearrange our equation to get our variable terms (8x and 4x) and our constants (the two 3's) together:

8x+4x-3-3

Taking away 3 twice is the same as taking away 6, and if we have 8 x's and add another 4 x's, that's the same as 8 + 4 = 12 x's, which we can write as 12x. So our simplified expression becomes

12x-6

Answer:

b. 28x + 8y +2

Step-by-step explanation:

you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.

-2*3x= -6x

-2*12y= -24y

-2*-5= 10 (remember neg times neg = pos)

-2*17= 34x

-2*-16y=32y

-2*4= -8

Now combine like terms

34x-6x= 28x

32y-24y=8y

10-8=2

Write the expression:  28x + 8y +2

Answer:

x = 51°

Step-by-step explanation:

The straight line segment has a total angle of 180°. Therefore, to find the angle inside the triangle that is next to 94°, subtract 94 from 180:

180° - 94° = 86°

That angle is almost a right angle but not quite. Now, to find x, add up the two angles inside the triangle and subtract it from 180°:

43° + 86° = 129°

180° - 129° = 51°
