I'm using PEDMAS.

Multiplication first.

2 • 4 = 8

Subtraction.

20 - 4 = 16

16 + 8 = 24

Please let me know if you spot any errors (especially the fraction operation)

Sara can take no more than 22 pounds of luggage on a trip. Her suitcase weighs 112 ounces. How many more ponds can she pack with

Elena L [17]

112oz(lb/16oz)+x≤22

7+x≤22

x≤15

So she can pack 15 more pounds without going over the limit.

The critical points of a rational inequality are –1, 3, and 4. Which set of points can be tested to solve the inequality? x = 1

never [62]

Answer:

x=-3, x=1, x=3.5, and x=5

Step-by-step explanation:

Given the critical points (turning points) which represent the maximum or the minimum points, the set of points that can be tested to solve the inequality will consist of points to the right and to the left of these points. The set of points that solve the inequality will be simply the points where the graph of the function crosses the x-axis. From these information, the set of points will be as given above
