Answer:
x = 12
Step-by-step explanation:
Supplementary angles, sum = 180
10x - 20 + 6x + 8 = 180
16x - 12 = 180
16x = 192
x = 12
Setup
remember is means =, and of means *
Writing across the words
15 = x * 39
15/39 = x
x =0.3846 = 38.46%
Step-by-step explanation:
Y=-4x+3
2x+3y=19
2x+3(-4x+3)=19
2x-12x+9=19
-10x=10
X=-1
y=-4*(-1)+3=4+3=7
x=-1 y=7
