Answer:
i hope this helps you :)
Explanation:
1.) 130
2.) 56
3.) 5
4.) 10
5.) 24
6.) 91
1.) 180 - 80 = 100
100 - 50 = 50
180 - 50 = 130
2.) 180 - 76 = 104
180 - 20 = 160
160 - 104 = 56
3.) 16x - 5 + 50 = -5 + 26x
add 5 to both sides 16x + 50 = 26x
take 16x from both sides 50 = 10x
divide both sides by 10 5 = x
flip the equation around x = 5
plug in the x value to the original equation 26 * 5 = 130
130 - 5 = 125
4.) x + 10 + 8x - 4 = 96
combine like terms 9x + 6 = 96
take 6 from both sides 9x = 90
divide all by 9 x = 10
plug in the x value into the equation 10 + 10 + 90 = 110
180 - 110 = 70
5.) looking for the measure of angle C
given 3x - 6 + 69 = 8x + 13
combine like terms 3x + 63 = 8x + 13
take 13 from both sides 3x + 50 = 8x
take 3x from both sides 50 = 5x
divide both sides by 5 10 = x
flip the equations around x = 10
plug in the x value to the angle of C 3x - 6
30 - 6 = 24
6.) find the value of angle JAB
12x - 5 = measure of angle JAB
given 7x - 4 + 39 = 12x - 5
combine like terms 7x + 35 = 12x - 5
add 5 to both sides 7x + 40 = 12x
take 7x from both sides 40 = 5x
divide both sides by 5 8 = x
flip the equation x = 8
plug in the x value to the equation of JAB 12x - 5
96 - 5 = 91
