1. 6 feet long
2. The border increases the length of each side by 1 foot
3. The width of the border is 6 inches (0.5 feet) because it adds on 1 foot in length to each side. Splitting it between the 2 borders for each side would make it 6 inches.
B, X is any number greater than or equal to 19.
Answer:
Step-by-step explanation:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Let m be the total mileages for each company.
Company A.
The total cost for m miles for this company is:
Company B.
The total cost for miles for this company is:
Now, we need to know for what mileage company A charges more than company B, this means:
Solving for m we have:
Therefore for m>140 (that is for more than 140 miles) company A will charge more tan company B.
Y=-2x+1 would be your answer! have a great day!
