System A: The system has exactly one solution (3,1)
System B: No Solution
System C: Infinite many solutions
Eh 12/20 is .6 pages a minute. 20/32 is .625 pages a minute
Answer:
250
Step-by-step explanation:
Line it up least to greatest
187,199,211,250,298,347,362
Cut each one off at each ends until middle
250
Radius is 142
You must find the diameter
Want to find diameter you need to take the number of radius is 142 Multiply 2
= 284
The circumference is 284
<span>a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.
b) are there any restrictions on the variables?
The total sum of both activities must be equal or less than $80 a month
c) write a linear inequality to represent this situation
</span><span>Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.
5x + 4y <u><</u> 80
You can graph linear inequality using these coordinates.
x y
16 0
12 5
8 10
4 15
0 20</span>
