Answer:

Step-by-step explanation:
First, find the LCM and multiply through:

The LCM will cancel out the denominators (note that braket symbolizes Multiplication):
:3(2x-1) +4(x)=24
:6x-3+4x=24
Group like terms:
6x+4x=24+3
10x=27
Divide through by 10 to eliminate the coefficient of x

Answer:
480ft squared
Step-by-step explanation:
length= 40*0.30= 12

Answer:
x=9/2 or 4.5
Step-by-step explanation:
First off.. we need to get the units the same. All in hours,
or all in minutes. 36 minutes = 36/60 hours = 3/5 hours = 0.6 hours.
12 minutes = 12/60 hours = 1/5 hours = 0.2 hours
Set up a proportion:
0.2 is to 0.6 as x is to 22.5
x/22.5 = 0.2/0.6
x = 0.2(22.5)/0.6
x = 7.5 hours
