Answer:
9) x = 89°
10) x = 118°
11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89
10) x = 118° because it is alternate interior to 118
11) x-30 = 115, x = 145
12) 4x-15 = 145, 4x = 160, x = 40
Answer:
x=8
Step-by-step explanation:
7x-5=3(x+9)
distribute
7x-5=3x+27
-3x -3x
4x-5=27
+5 +5
4x=32
÷4 ÷4
x=8

For these, we just have to expand then collect like terms.
1) 4x^+2x+4x+2 ~ 4x^+6x+2
2) 6x^+12x+2x+4 ~ 6x^+14x+4
3) 6x^+12x+3x+6 ~ 6x^+15x+6
4) 5x^+5x+2x+2 ~ 5x^+7x+2
Hope these help, have a great day
2 is equivalent to 6/3
2/3 + 2/3 = 4/3 4/3 + 2/3 = 6/3
