Answer:
The equation of line AB with points (3,3) and (-3,5) is given as
: x + 3y = 12
Step-by-step explanation:
Here, the given points are A (3, 3) and B (-3,5).
Now, slope of any line is given as :
or, 
Hence, the slope of the line AB is (-1/3)
Now , A POINT SLOPE FORM of an equation is
(y - y0) = m (x - x0) ; (x0, y0) is any arbitrary point on line.
So, for the point (3,3) the equation of the line is
y - 3
Hence, the equation of line AB with points (3,3) and (-3,5) is given as:
x + 3y = 12
Answer:
A.) Eric rode 2 more miles per week than Kim rode
Step-by-step explanation:
A.) Eric rode 2 more miles per week than Kim rode
B.)Kim rode 3 more miles per week than Erick rode
C.) Kim rode 11 more miles per week than Erick rode
D.) Eric rode 17 more miles per week than Kim rode
Kim rode her biyciclye 135 miles in 9 weeks.
Number of miles Kim rode per week = Total miles travelled / number of weeks
= 135 miles / 9 weeks
= 15 miles per week
Eric rode her biciclye 102 miles in 6 weeks
Number of miles Eric rode per week = Total miles travelled / number of weeks
= 102 miles / 6 weeks
= 17 miles per week
The correct answer is
A.) Eric rode 2 more miles per week than Kim rode
115*20=2300.
50*5=250
First mechanic 20 hours
Second mechanic 5 hours
Answer:
$2.50
Step-by-step explanation:
If it costs $5 for two hours and one hour is half of two hours, you take half of $5 and use it as your answer, so your answer is $2.50
Answer:
A. 8 gallons
B. Drive by car is $59.4 cheaper than travel by train
Step-by-step explanation:
According to the scenario, given data are as follows,
Total drive = 400 miles
Total drive per gallon = 50 miles
Fuel cost per gallon = $4.45
A. So, Total fuel required to drive 400 miles can be calculated as follows,
Total fuel required = Total drive ÷ Total drive per gallon
By putting value, we get,
Total fuel required = 400 ÷ 50
= 8 gallons
B. Total cost if drive by car = 8 gallons × $4.45 = $35.6
Cost if travel by train = $95
Hence it is clearly shows that drive by car is much cheaper than travel by train.
Cost saved by travel by car = $95 - $35.6 = $59.4
So, drive by car is $59.4 cheaper than travel by train.
