Answer:
300 minutes
Step-by-step explanation:
Let
x----> the numbers of minutes used
y ---> the cost per month
we know that
<em>First cell phone plan</em>
y=0.15x+20 ---> equation A
<em>Second cell phone plan</em>
y=0.10x+35 ---> equation B
equate the equation A and equation B
0.15x+20=0.10x+35
Solve for x
0.15x-0.10x=35-20
0.05x=15
x=15/0.05
x= 300 minutes
Find the cost y
y=0.15(300)+20 =$65
That means
For x=300 minutes
The cost for both calling plans is y=$65
You are given following <u>data</u>:
15 logs - 10 hours,
9 logs - x hours.
Use <u>proportion</u> to determine unknown <u>value</u> of x:
Then
Answer: 6 hours
The answer is C because you can have a triangle with 5,9,n 5,10,n 9,10,n and 5,10,9
The reason why is because the sum of two sides is always larger than the value of the third side.
