Answer:
x = -11
Step-by-step explanation:
First, add three to both sides on the equation. Then, your equation becomes 55= -5x. Finally, divide both sides by -5 to get -11 = x. So, x equals -11. Hope this helps!
Answer:
27 degrees
Step-by-step explanation:
5t - 13 = 3t + 3
subtract 3t on both sides
2t - 13 = 3
add 13 to both sides
2t = 16
divide by 2 on both sides
t = 8 degrees
Now, plug in 8 to the measure of x
5(8) - 13 = 27

Answer:
<ABC = 49°
Step-by-step explanation:
The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;
3x+4+8x+11 = 180
11x+15= 180
11x = 180-15
11x = 165
x = 165/11
x = 15
From the attached diagram, <ABC = 3x+4
<ABC = 3(15)+4
<ABC = 45+4
<ABC = 49°
