Answer:
4x°= 4x18= 72°=measure of angle SQR
Step-by-step explanation:
6x +4x = 180
10x = 180
x = 180/10
x= 18°
because m L SQR =4x°
now place the value of x in the above equation
m L SQR = 4 x(18°)= 72°
Given:
Joining fee = $28
Fee of each event = $4
To find:
Total cost for someone to attend 4 events.
Solution:
Let the number of events be x and total fee be y.
Fee for 1 event = $4
Fee for x events = $4x
Joining fee remains constant. So, the total fee is

Substitute x=4 in this equation.



Therefore, total cost of 4 events is $44.
Pineapple juice : orange juice : lime juice = 2:7:3
