What is the value for x if the perimeter is 45

11

Step-by-step explanation:

Perimeter of the triangle = 45

x + x + 7 + x + 5 = 45

3x + 12 = 45

3x = 45 - 12

3x = 33

x = 33 /3

x = 11

Student council

XXX

Number of snow cones:

XXX

Number of hours spent making snow cones:  

4

Number of snow cones per hour:
