Answer:

x = 11/2 = 5^1/2 =5.5

Step-by-step explanation:

1/2(4x-12)=5

Multiply both sides by 2, the reciprocal of 2/1 =0.5

4x−12=5×2

Multiply 5 and 2 to get 10.

4x−12=10

Add 12 to both sides.

4x=10+12

Add 10 and 12 to get 22.

4x=22

Divide both sides by 4.

x = 22/4

Reduce the fraction 4/22 =5.5 to lowest terms by extracting and canceling out 2.

x = 11/2

Answer: $24\ liters$

Step-by-step explanation:

Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.

1. In the first part of the trip the amount of gasoline the car used can be expressed as:

$\frac{2}{3}x$

2. After the first part of the trip, the remaining was:

$x-\frac{2}{3}x=\frac{1}{3}x$

3. In the second part of the trip the car used $\frac{1}{2}$ of the remaining. This is:

$(\frac{1}{3}x)(\frac{1}{2})=\frac{1}{6}x$

4. The total amount ot gasoline used in this trip was 20 liters.

5. Then, with this information, you can write the following equation:

$\frac{2}{3}x+\frac{1}{6}x=20$

6. Finally, you must solve for "x" in order to find its value. This is:

$\frac{2}{3}x+\frac{1}{6}x=20\\\\\frac{5}{6}x=20\\\\5x=120\\\\x=24$

Which fraction is least to greatest ??

marshall27 [118]

First, write each fraction so that it has a common denominator.

A common denominator for 5/6 and 3/5 is

Y_Kistochka [10]

factors of 6: 6 12 18 24 30

factors of 5: 5 10 15 20 25 30

so its 30

or simply multiple the denominators 6×5=30
