Answer:
- The third side may be between 1 and 13 units
Step-by-step explanation:
Let the missing side is x.
According to the triangle inequality theorem, the sum of any two sides of a triangle is greater than the third side.
<u>We have inequalities:</u>
- 6 + 7 > x ⇒ x < 13
- 6 + x > 7 ⇒ x > 1
- 7 + x > 6 ⇒ x > - 1
<u>The common solution is:</u>
Each day she eats 1/2 cups of rice. But we want to know how long it will take to each 2 cups worth. so lets make an equation.
.5x = 2
Divide both sides by .5
x = 4
So it will take 4 days to eat 2 cups of rice cereal.
