Answer:
The slope is $0.35/min and it gives the cost per minute of the phone used.
Step-by-step explanation:
We can model this situation with a linear equation of the form

where
is monthly cost,
is the number of minutes,
is the flat monthly fee, and
is the slope of the equation, or in our case, the amount of money charged per minute.
The slope
is

,
in other words, the phone company charges $0.5 per minute.
With the slope in hand, the linear equation becomes
,
and we can find the monthly fee
from that fact that for 300 minutes the cost is $131:

.
Therefore,

where the slope if the equation give the cost per minute of the phone used.
Answer:
1 mile = $14
Step-by-step explanation:
We know how much the 18-mile trip is for sale, so to know how much 1-mile sale we just have to divide the total amount by the amount of miles
18 miles = $ 249
1 mile =
1 mile = 249 / 18
1 mile = 13.83
To know what the nearest dollar value is, we only have to check if what is after the whole number is May or less than .50
is larger so we round to the largest number that is 14
nearest dollar = $14
Answer: $35
Step-by-step explanation: If three pairs of shoes cost 26.25 you need to divide that by 3 to get the individual price of each pair of shoes, then add the price of the shoe individually to 26.25 and you will get your answer.
I don't really like these algebra problems which pretend to be geometry.
The bisector makes two equal angles, so
x/2 + 17 = x - 33
50 = (1/2) x
x = 100
That means ABC = 100/2 + 17 = 67 degrees
CBD = 100 - 33 = 67 degrees, equal so that checks
We're asked for ABC which is 67 + 67 = 134 degrees
Answer: 134°
