Dora and james are selling tickets to a concert. Dora sold 3 student tickets and 3 adult tickets for a total of $69. James sold 5 student tickets and 3 adult tickets for a total of $91

Student ticket cost $11

Adult ticket cost $12

Step-by-step explanation:

Let number of student ticket be x and adult ticket be y

3x+3y=69

5x+3y=91

Subtract above equation you get

-2x=-22

x=11

Since 3x+3y=69 will

x+y=23 by dividing throughout by 3

y=12

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
