Answer:
-5
Step-by-step explanation:
y=-2/3-5x
Rewriting the equation in the form y = mx+b where m is the slope and b is the y intercept
y = -5x -2/3
The slope is -5 and the y intercept is -2/3
using X for your mystery number, the answer is:
x + 11 · x + 8
26 / 8 = 3.25;
14 / 4 = 3.50;
The mistake is obvious !
14x-5=65 ( vertically opposite angles)
14x=65+5
14x=70
x=5
z= 180-65= 115
