Answer:
23 tables were used that day at lunch.
Step-by-step explanation:
203 - 19 = 184
184 ÷ 8 = 23
x = 5/8
24a = 15
Divide both sides by 24:
24a ÷ 24 = 15 ÷ 24
a) a *5+5= 20
5a + 5 = 20
5a = 20 - 5
5a = 15
a = 15/5
a = 3
b) b/5 - 5 = 4
b/5 = 4 + 5
b/5 = 9
b =9*5
b = 45
x=3/7
x+4 5/7 = 12x
4 5/7 = 11x
x = 3/7
