To solve this proportion:

Simplify 3/6, it reduces to 1/2

Then do the Criss cross method
1d = 7 ×2
d=14
Hope it helps!
Answer:
8/21
Step-by-step explanation:
Answer:
a. It would cost $77.50 to buy 5 tickets.
C(x)=17.5(5)-10
C(x)=87.50-10
C(x)=77.50
b. You can buy 8 tickets with $130
C(x)=17.5x-10
130=17.5x-10
Add 10 on both sides
140=17.5x
Divide 17.5 on both sides
8=x
Check the picture drawn
Consider the line segment AB,
let M be the midpoint of AB, so AM=MA
erect the perpendicular MT to AB from point M. Pick a point P on MT and join it to the points A and B
The triangles PMA and PMB are congruent from the Side Angle Side congruence postulate:
AM=MA, PM is common and m(PMA)=m(PMB)=90°, as MT is perpendicular to AB
so PA=PB
Answer:
Horizontal line has a slope of 0
