C 12 minutes is the correct answer. Hope this helps :)
I think its 1.25ft but i could be wrong... sorry if im wrong
Ok so first you will need 3 bags since 12*2 is 24 that wont be enough for the whole class so 12*3= 36 so now that we figured out how many bags we need now we have to multiply $8.00 by three the answer is $24
Answer:
Step-by-step explanation:
Rule Example
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6
Step 1: Find common denominators
LCM of 2 and 4 = 4
2 3/4 - 1 2/4
Step 2: Subtract
2 - 1 = 1
3/4 - 2/4 = 1/4
Answer: 1 1/4
Hope this helps!! :)
