Answer:
x=8
Step-by-step explanation:
2(x+4) - 10 =14
distribute the 2 2x +8 -10 +14
simplify 2x-2=14
add 2 2x=16
devide by 2 x=8
Answer:
12
Step-by-step explanation:
Because I think it is
Answer:
y=
x-6.5
Step-by-step explanation:
=
= 
y=mx+b
-8 = (
) (-6) +b
-8 = -
+b
b= -6.5
Step-by-step explanation:
5x+3x-14=180
8x-14=180
8x=180+14
8x=174
x=174/8
x= 21.75°
if x is 21.75°, then 5x is 108.75°
which means 3x-14 is 51.25°
therefore, f +108.75+51.25=180
f = 180-160
f=20°
