Answer:
<em>y=0.10(t)+0.25 </em>
<em>27 minutes and 30 seconds </em>
Step-by-step explanation:
We know that you start with 25 cents as a service fee, this is for making the call. For each minute you talk, 10 cents are added. Multiply the number of minutes spent by 10 cents a minute for the cost based on the call. Then add the 25 cents service fee.
If you talked for 5 minutes:
y=0.10(5)+0.25
y=0.50+0.25
y=0.75
75 Cents
For three dollars, you would plug in 3 for y
3.00=0.10(t)+0.25
-0.25 -0.25
2.75=0.10(t)
divide both sides by 0.10 to get
27.5=t
You can talk for 27 minutes and 30 seconds
27 minutes

Since 6 + 8 = 14 this is the longest that the third side can be.
The answer is B
12x+2y=112
6x+y=56
6x=56-y
x=(56-y)/6
y=(56-6x)
Given that B is a point between point A and C, the numerical value of x is -5.
<h3>What is the numerical value of x?</h3>
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given the data in the question;
- B is a point between point A and C
- Segment AC = 14
- Segment AB = x + 12
- Segment BC = x + 12
- Numerical value of x = ?
Since B is a point between point A and C.
Segment AC = Segment AB + Segment BC
Plug in the given values and solve for the value of x
Segment AC = Segment AB + Segment BC
14 = (x + 12) + (x + 12)
14 = x + 12 + x + 12
14 = 2x + 24
2x = 14 - 24
2x = -10
x = -10/2
x = -5
Given that B is a point between point A and C, the numerical value of x is -5.
