jan's gas tank is nearly empty, at 1/12 full. she doesn't have enough cash to fill the tank, she adds enough gas to reach 2/3 full.
How much gas did she add, as a fraction of the tank?

Answers

Answer 1

Answer:

7/12

Step-by-step explanation:

well first you have subtract 2/3 from 1/12 how you do that is that you have to change the denominator into twelve by multiplying 3 times 4 and 2 times for which you get 8/12 them subtract 8/12 from 1/12 which is 7/12

Answer 2

If Jan's tank is 1/12 full and after addition it becomes 2/3 full then she added 7/12 gas as a fraction of tank.

What is fraction?

Fraction is a combination of two numbers one in numerator and the other one in denominator. The number which is above the division sign is known as numerator and the number which is below the division sign is known as  denominator. It is expressed as v/u where v is numerator and u is denominator.

How to calculate fraction?

Initial quantity of gas is 1/12 of the tank.

Quantity of gas after filling is 2/3 of the tank.

So the initial fraction is 1/12 and final fraction is 2/3.

let the fraction of gas added be x.

So,

1/12+x=2/3

x=2/3-1/12

x=(8-1)/12

x=7/12

Hence the gas which is added by Jan is 7/12 fraction of the tank.

Please anyone help me The measure of an angle is five times the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

150 and 30

Step-by-step explanation:

Hello!

Supplementary angles are angles that when added up equal 180

Which can be shown by

x + x = 180

Since one has to be 5 times bigger we put a 5 in front of one of the x's

5x + x = 180

5x is an angle and x is the other

Now we solve for x

5x + x = 180

Combine like terms

6x = 180

Divide by 6

x = 30

Now we put that into each angle

5(30) = 150

30

The answer is 150 and 30

Hope this Helps!

Hello!

Answer:

Each angle; the answer is 30 & 150

Step-by-step explanation:

So let say that the supplement is ‘X’.... You want to find the angle of 5x

Therefore, 6x=180 (X=30)

Since we found out one angle out which is 30.

Now you find 5x.

5x30 and you will get 150.

So the angles of each is “30” and “150”.

Hope this helps!
