Answer:
see below
Step-by-step explanation:
22% is close to 20 % = .2 in decimal form
78 is close to 80
.2 * 80 = 16
If the answer is close to 16 then it is reasonable
22% of 78 = 17.16
x² - 13x + 30 = 0
Factorise:
(x - 3) (x - 10) = 0
Apply zero product property:
x - 3 = 0 or x - 10 = 0
Evaluate:
x = 3 or x = 10
Answer: x = 3 or x = 10
Answer:
4 of the next 10 will be lattes
Step-by-step explanation:
8 /20 were lattes
divide top and bottom by 4

4 of the next 10 will be lattes
It is between c 12 and d 13
12 cartons will be 15
and 13 will be 16.3
