Answer:
Inequality: [tex]100+x\leq 700[/tex]
Solution: [tex]x\leq600[/tex]
Step-by-step explanation:
For this exercise it is important to remember the meaning of the symbols of inequalities. These are:
[tex]<[/tex] means "Less than".
[tex]>[/tex] means "Greater than"
[tex]\leq[/tex] means "Less than or equal to".
[tex]\geq[/tex] means "Greater than or equal to".
Let be "x" the additional volumes (in cubic inches) the pelican's bill can contain.
According to the information provided in the exercise, you know that the maximum volume of an American white pelican's bill is about 700 in³.
Knowing this and knowing that a pelican scoops up 100 in³ of water, you can write the following inequality:
[tex]100+x\leq 700[/tex]
In order to solve for "x", we must subtract 100 from both sides of the inequality to represents the additional volumes the pelicans's bill can contain.
Then you get:
[tex]100+x-100\leq 700-100\\\\x\leq600[/tex]
