Answer:
12
Step-by-step explanation:
A straight line is equal to 180. The line AB is 180 degrees. This means 174 + angle = 180 for the angle between point D and B. It must be 6 degrees. This is the same angle as the angle between point A and C.
Line CD is also straight and equal to 180. On the line are the angles, 4k + 90 + 3k + 6 = 180. Solve for k by combining like terms and then using inverse oeprations.
4k + 90 + 3k + 6 = 180
7k + 96 = 180
7k = 84
k = 12
Answer:
a=40. b=140. c= 40
Step-by-step explanation:
b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.
a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.
c is Congruent to a due to the vertical angles postulate
Complete question :
Christelle and Larkin both drive customers on the weekend. Christelle charges a flat fee of $4, plus $1 per mile. Larkin charges a flat fee of $2, plus $1.25 per mile.
Which equations represent each of their earnings, (y), after a given number of miles, (x)?
Select two that apply. Put more then one answer
y=4x+4
y=x+4
y=2x+1.25
y=1.25x+2
y=−x−4
y=1.25x−2
Answer:
y=x+4
y=1.25x + 2
Step-by-step explanation:
Christelle:
Flat fee = $4
Charge per mile = $1
Earning, y after x miles
y = 4 + x
Lakin:
Flat fee = $2
Charhe per mile = $1.25
EEarning, y after x miles
y = 2 + 1.25x
