Answer=6
Given the information, the following equation can be made, where x is equal to the number of cases she needs to buy.
160=16+24x
subtract 16 from both sides
144=24x
divide both sides by 24
6=x
She will have to buy 6 cases to have a total of 160 water bottles.
The answer to the problem is y^12
Number of toothpicks required per student = At least 9
Total number of students = 30
Number of toothpicks required for the entire class = At least 9 × 30 = At least 270
Number of toothpicks in the bag in the class storage room = 50
Additional number of toothpicks required to be bought to make sure there are enough toothpicks = 270 - 50 = 220
Hence, she needs to buy 220 toothpicks.
Answer:
9
Step-by-step explanation:
So the greatest 2 digit number is 99 and the greatest 3 digit number is 999
So find the hcf ( highest common factor ) of 99 and 999.
Factors of 99 : 1, 3, 9, 11, 33, 99
Factors of 999 : 1, 3, 9, 27, 37, 111, 333, 999
Common factors : 1, 3, 9
Hcf : 9
