Add 2x and subtract 7
5 -2x +2x < 7 +2x . . . . . . showing 2x added
5 < 7 +2x . . . . . . . . . . . .. simplified
5 -7 < 7 -7 +2x . . . . . . . . showing 7 subtracted
-2 < 2x . . . . . . . . . . . . . . . simplified
Now, divide by 2
-1 < x
The solution is -1 < x.
Answer: 0.1 liter
Step-by-step explanation:
From the question, we are informed that Brianna teacher gives her a container that has 0.25 liter of a liquid in it and she needs to use 0.4 of this liquid for the experiment.

Answer:
25,000 grams
Step-by-step explanation:
Density can be found using the following formula:

If we rearrange the formula for
, mass, we will multiply both sides of the equation by v.


The mass can be found by multiplying the density by the volume.
Jeff's density is 1000 grams per milliliter and his volume is 25 milliliters.

Substitute the values into the formula.


Multiply. When you multiply, the "mL" or milliliters will cancel out.


Jeff's mass is 25,000 grams.
