Eva8 [605]3 years ago
8 0

Answer:

41

Step-by-step explanation:

the sum of all 3 terms must equal 180 because triangles have 180 degrees. knowing this we can add all the terms together to get 4x+16=180. subtract 16 on both sides to isolate the variable and you get 4x=164 divide both sides by 4 to solve and you get 41

Zinaida [17]
H + c = 605
c = h + 55

h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday

c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday
