Solve for x: (x+4)/2=7 * (x+4)/2 is a fraction *

blondinia [14]

Answer:

x=10

Step-by-step explanation:

So, we got our equation:

$\frac{x+4}{2}=y$

We'll multiply both sides by 2 to get rid of that fraction.

x+4=14

Then, we just subtract 4 from both sides.

x=10

Carlos has \dfrac45 5 4 start fraction, 4, divided by, 5, end fraction of a tank of fuel in his car. He uses \dfrac{1}{10} 10

Tresset [83]

Answer:

8 days

Step-by-step explanation:

We are told in the question:

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.

How many days will his fuel last?

1/10 of fuel = 1 day

4/5 of fuel = x

Cross Multiply

1/10 × x = 4/5 × 1

x = 4/5 / 1/10

x = 4/5 ÷ 1/10

x = 4/5 × 10/1

x = 8 days

His fuel lasts for 8 days
