Your time spent playing pool and ice skating must not exceed 20 hours a week. Your weekly allowance is $80. You pay $3 an hour p
Anton [14]

Answer:

The graph in the attached figure

Two possible solutions are the point (10,10) and the point (4,8)

see the explanation

Step-by-step explanation:

Let

x ----> the time in hours spent playing pool in a week

y ----> the time in hours spent for ice skating in a week

we know that

x+y \leq 20 ----> inequality A

3x+5y \leq 80 -----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that the time can not be a negative number

If a ordered pair is a solution of the system of inequalities, then the ordered par must lie on the shaded area of the solution

Looking at the graph

Two possible solutions are

(10,10) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 10 and the time in hours spent for ice skating in a week is 10

(4,8) ----> this point lie on the shaded area of solution

That means -----> The time in hours spent playing pool in a week is 4 and the time in hours spent for ice skating in a week is 8

When you have two side lengths of 2in and 4.5in What is the other side length?
nika2105 [10]

Answer:

The solution for the other side length is the interval

(2.5,6.5)

Step-by-step explanation:

I will assume that is a triangle

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ---> the measure of the third side

Applying the Triangle Inequality Theorem

1) 2+4.5 > x

6.5 > x

Rewrite

x < 6.5\ in

2) 2+x> 4.5

x> 2.5\ in

therefore

The solution for the other side length is the interval

(2.5,6.5)
