Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
Answer:
465 minutes or 8 hours and 15 minutes
Step-by-step explanation:
her monthly bill was 72.25 and she has to pay 2.50 per month
72.25 - 2.50 = 69.75
69.75/ 0.15 = 645 minutes
645 minutes/ 60 minutes= 7.75 = 8 hours 15 minutes
Answer:
10 classes
Step-by-step explanation:
Ok, so to solve this we have to make two different equations. we can say 60x = y, or $60 per month, and 6a = b, or $6 per walk in. Since we want the options to end up costing the same, we can say that y = b. With substitution, we get that 60x, (60 per month) = 6a (6 per drop in). The question says we have 1 month, so x = 1. This means we have 60 = 6a, and a = 10 (10 classes).
Answer:
Step-by-step explanation:
Let x be the number of miles.
We have been given that Sully's car has an average fuel economy of 28 miles per gallon. The capacity of the fuel tank is 16 gallons.
Let us find the number of miles that Sully can drive with 16 gallons.
This means that initially Sully's car has can drive 448 miles, so at x equals 0, y will be 448.
As the car consumes 1 gallon for each 28 miles driven, so the gallons of fuel consumed in traveling x miles will be 28x. As each gallon of fuel will decrease with each 28 miles traveled, so slope of our function will be -28.
Upon substituting slope and y-intercept in slope-intercept form (y=mx+b), we will get our function as:
Therefore, our required function will be: .
Answer:The answer is 98
Step-by-step explanation:
Median is the middle number, so put the numbers from least to greatest and pick the number in the middle. In this case: 43,56,98,106,112. 98 is in the middle.
