Answer:
x=19
Step-by-step explanation:
9*(9+15)=8*(8+x)
9*(24)=8(x+8)
216=8x+64
216-64=8x+64-64
152=8x
152/8=8x/8
19=x
x=19

B because it makes the most sense to me
Answer:
Check explanation.
Step-by-step explanation:
slope-intercept form: y=mx+b
9x+5y=23
5y=-9x+23
y=-9/5x+23/5
m=slope: -9/5
b=y-intercept: 23/5
Answer:
x = 10
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, then
5x - 9 = 3x + 11 ( subtract 3x from both sides )
2x - 9 = 11 ( add 9 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
