Answer:
x=574
Step-by-step explanation:
it says that on my caculater.
3 and 3/4lb=20.25
what you should do is divide both sides by 3 and 3/4 but that isnt nice
convert 3 and 3/4 to improper
3 and 3/4=3+3/4=12/4+3/4=15/4
15/4lb=20.25
times 4/15 to both sides (15/4 times 4/15=60/60=1)
1lb=81/15
1lb=5.4
answer is
1lb=$5.40
Step by step
distribute= 4y-12+20y
combine like terms =24y-12
therefore answer is C
It should be 0.4 cause 0.4 is the same as 0.40
10 kilometers per hour
