A triangle has side lengths of 12, 15, and x. The value of x must ne greater than what?

Bezzdna [24]

Answer:

3 < x < 27

Step-by-step explanation:

We can't tell what "must ne greater" means, so we'll tell you the limits on the side length and you can choose the one that is relevant.

The third side of a triangle must have a length that lies between the difference and sum of the two lengths you know.

15 -12 = 3

15 +12 = 27

The value of x must be between 3 and 27:

3 < x < 27

If you allow the triangle to have zero area, then x can be 3 or 27. Many authors claim such a "triangle" is not allowed, so don't allow those cases.

Elyse uses 42 gallons of water in a 10-minute shower. Write and solve a prediction problem that uses this information

kvv77 [185]

Let

x-----> the time in minutes

y------> the number of gallons of water

we know that

the unit rates is equal to

$\frac{y}{x} = \frac{42}{10}=4.2\frac{gal}{min}$

the unit rate is equal to the slope of the linear equation

then

$y=4.2x$

Problem

1) How many gallons of water will Elyse use in three minutes in the shower?

For x=3 minutes

substitute in the equation above

$y=4.2x$

$y=4.2*3$

$y=12.6 gal$

the answer is

12.6 gal
