notice that, if Q is the midpoint of PR, that simply means that PQ = QR = 43.

The third one is right i think
Answer:
416.444 pounds
Step-by-step explanation:
Drum of alcohol = 50 gallons

50 gallons drum of alcohol = 416.444 pounds of alcohol to the nearest hundredth pound.
Step-by-step explanation:
12x-8=64
we transposed
12x=64+8
12x=72
we divide both by 12
12x/12=72/12
x= 6
Answer: You are right.
Step-by-step explanation: The amount of gas you have will only get you 115.2 Miles and the gas station is 116 miles away.
19.2 % 3 = 6.4
