Answer:
351 adults and 275 students
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.
We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.
We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.
s+a=626
s+76+s=626
2s+76=626
2s+76-76=626-76
2s=550
s=275
This means that 275 students attended and 351 adults attended since 275+351=626.
When the dilation is around the origin, we just have to multiply each coordinate by the scale factor.
We're starting from A(2,2), B(2,5), C(6,5) and D(6,2) and scaling by 3 so the image A'B'C'D' is
Answer: A'(6,6), B'(6,15), C'(18,15), D'(18,6)
