Answer:
There are many ways to interpret if whether or not a system of equations has solutions or not. Here is one way that is most ideal for most, if not, all equations: using graphs.
- If the graphs of the set of equations do NOT intersect, then there are no solutions (because no x or y value will ever make both equations true)
- If the graphs of the set of equations DO intersect at one point, then ONLY that one point will make both equations true. (One solution)
- If the graphs of the set of equations are identical on the graph, then there are infinite solutions that make both equations true.
1.
20 pounds of strawberries
5 persons
20 ÷ 5 = 20 pounds ÷ 5 persons = 4 pounds per person
Answer: 4 is the pounds per person, how much each person received
2.
20 pounds of strawberries
5 pounds per person
20 ÷ 5 = 20 pounds ÷ 5 pounds/person= 4 persons
Answer: 4 is the number of people we're splitting among
|x-10| when x = -8
| - 8 - 10 | = |-18| = 18 <==
Answer: They read for a equal amount of time.
Step-by-step explanation:
10/12 simplifies to 5/6, making these equal.
Proof:
10 divided by 2 equals 5, and 12 divided by 2 equals 6. This means that they are equal.
