Answer:
Step-by-step explanation:
Simplifying
4x + 11 = k
Reorder the terms:
11 + 4x = k
Solving
11 + 4x = k
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 4x = -11 + k
Combine like terms: 11 + -11 = 0
0 + 4x = -11 + k
4x = -11 + k
Divide each side by '4'.
x = -2.75 + 0.25k
Simplifying
x = -2.75 + 0.25k

Answer:
<4 = 88
<3 = 92
Step-by-step explanation:
The sum of the angles of a triangle is 180
<4 + 45+ 47 = 180
<4 + 92 = 180
< 4 = 180-92
<4 = 88
We know the <3 and <4 form a line
<3 + <4 = 180
<3 + 88 = 180
< 3 = 180-88
<3 = 92
X=13 and z=112
you know that (13x-57) + (6x-10) = 180 since they are supplementary, so you will solve that. it will give you x=13. now that you know x, you can solve for z by plugging in 13 for x on 13(x)-57 since that and angle z are congruent. when you simplify, you will get z=112.
you can check your answer by doing (6x-10) +112=180. this is because they are supplementary. you should get x=13, and that is how you know you are right.
