Answer:
C
Step-by-step explanation:
Let's use the formula!
6/-4 - -2/-4 = 8/0.
Since this is divided by 0, this means that it is undefined.
So C
Explanation:
Substitute:
3 for x
3 for y
1 for z
x(−y+z)
becomes:
3(−3+1)⇒
3 ⋅ −2 ⇒
−6
Answer:
70°
Step-by-step explanation:
∠A =112°,
Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)
Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x
∠A + ∠B + ∠C = 180 (sum o angles in a triangle)
112 + 180 - 2x + 168 - 2x = 180
460 - 4x = 180
4x = 460 - 180 = 280
x = 280/4 = 70
x = 70°
Answer:
Inf
Step-by-step explanation:
12 and 1/8 because you change 5 1/4 into 5 and 2/8. Then you add them togther and get 12 1/8
