7.1
X - 4.3 = 2.8
Add 4.3 to both sides
X = 7.1
Answer:
y = 3x
Step-by-step explanation:
y = mx + b
(x,y) = (1,3)
m = 3
3 = 3(1) + b
3 = 3 + b
3 - 3 = b
0 = b
y = 3x
Answer:
z=7
Step-by-step explanation:
72°+(8z-8)°+(9z-3)°=180° (a triangle contains 180° and vertical angles are equal)
(8z-8)°+(9z-3)°=180°-72°
17z°-11°=108°
17z°=108°+11°
17z°=119°
z°=119°/17°
z°=7°
z=7
