The tank can hold $12\frac{3}{4}$ gallons of gasoline when completely full. He had some gas in the tank and added 10.3 gallons of gasoline to fill it completely.

We need to find: How many gallons of gasoline were in the tank before Javier added some?

For this, we need to subtract added gallons of gasoline from the capacity of the tank.

$12\frac{3}{4}-10.3=\frac{51}{4}-10.3$

$=12.75-10.3$

$=2.45$

Hence, 2.45 gallons of gasoline were in the tank before.

kipiarov [429]

Explanation:
Sum of all angles= 180 degrees

So,
3x + 75= 180
3x= 180 - 75
3x= 105
x= 105/3
x= 35

Answer= 35 degrees

5y + 3 > −7y + 13 Multi-step linear inequalities

Artemon [7]

Answer:

y > $\frac{5}{6}$

Step-by-step explanation:

Given

5y + 3 > - 7y + 13 ( add 7y to both sides )

12y + 3 > 13 ( subtract 3 from both sides )

12y > 10 ( divide both sides by 12 )

y > $\frac{10}{12}$ , that is

y > $\frac{5}{6}$
