Order of operations rules are important here: n/4-13
We must do the division first. Thus, n/4-13 translates to "the quotient of n and 4, less 13."
Answer:
42°
Step-by-step explanation:
∠NML = ∠ZYX =88°
Angles in a triangle add up to 180 so ∠ZXY =
180 - (50+88)
180-138
42
∠ZXY = 42°

Answer:
8x + 5x = 13x
Step-by-step explanation:
Since these two can be added, you just add like normal and make sure you do not forget the x.
Answer:
a = - 2
Step-by-step explanation:
calculate the slope of the 2 given points and equate to 0.75
m = 
with (x₁, y₁ ) = (4, a ) and (x₂, y₂ ) = (8, 1 )
m = 
= 
then equating
= 0.75 ( multiply both sides by 4 to clear the fraction )
1 - a = 3 ( subtract 1 from both sides )
- a = 2 ( multiply both sides by - 1 )
a = - 2
