499.50 is the total amount of discounts given to senior citizens
Answer: |5x+1|-7
Step-by-step explanation:

We just have to solve to get a simplified answer
we have
9y + 5 = 7 + 3y + 2y
9y +5 = 7 + 5y
9y-5y= 7-5
4y=2
so if we solve further we will not get the answer that is given in option
so option d is the write answer
Answer:
C = 314 meters
Step-by-step explanation:
When we go around a circle, we are trying to find the circumference
The circumference is
C= pi *d
C = pi *100
Let pi = 3.14
C = 3.14*100
C = 314 meters
Is there a picture of the triangle or any measurements other than multiple choice
