Answer: 7.8
Step-by-step explanation: If we want to find the amount that was in the pitcher before then we subtract 2.6 from 10.4 to find the original amount because if the pitcher were to contain an amount that only adds up to 10.4 before we add 2.6 then the number that adds with 2.6 to equal 10.4 is our answer
hence our answer 7.8
This question tests one's knowledge of states of matter. Kim would have to classify the water as gaseous matter in this case.
<h3>Why should Kim classify the water as gaseous?</h3>
Remember, she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.
Matter can exist in various states. They are:
- Solids;
- Liquids;
- Gaseous;
- Plasma; and
- Bose-Einstein condensate. (which is Man-made).

Answer:
Step-by-step explanation:
-5x+31+3x=3
move everthing to one side
-5+31+3x-3=0
add and subtract common terms
-2x+28=0
divide across by common denominator
-x+14=0
Solve for x
x=14
Step-by-step explanation:
everything can be found in the picture
Recall that a slope-intercept form of a linear equation is

Rearrange the given so that it follows that slope intercept form

The y-intercept is the value for which the linear function crosses the y-axis, this is when the value of x is equal to zero. The ordered pair therefore of the y-intercept is (0,-1).
