The number of points that Pedro scored in the basketball game is represented by the equation 4y = 104x. In this equation, y represents the total number of points and x represents the number of games. How many points did Pedro average per game?
____ points per game.
____ points per game.
To find the average number of points Pedro scored per game, we divide the total number of points (y) by the number of games (x).
Since 4y = 104x then y = 104x / 4 = 26x
So, Pedro scored 26 points per game on average.
So, Pedro scored 26 points per game on average.
Pedro scored 26 points per game on average.
Since 4y = 104x then y = 104x / 4 = 26x
So, Pedro scored 26 points per game on average.
So, Pedro scored 26 points per game on average.
Pedro scored 26 points per game on average.
Determine the unit rate for 1 bag of chips if 5 bags cost $6.25; the proportional relationship is described by 5y = $6.25x .
Answer Choices:
* $0.80
* $31.25
* $1.25
* $1
Answer Choices:
* $0.80
* $31.25
* $1.25
* $1
To find the unit rate for 1 bag of chips, we need to divide the total cost by the quantity.
Given: 5y = $6.25x
$6.25 is the total cost for 5 bags of chips, so each bag of chips costs $6.25 / 5 = $1.25.
Therefore, the unit rate for 1 bag of chips is $1.25.
So, the correct answer is:
- $1.25
Given: 5y = $6.25x
$6.25 is the total cost for 5 bags of chips, so each bag of chips costs $6.25 / 5 = $1.25.
Therefore, the unit rate for 1 bag of chips is $1.25.
So, the correct answer is:
- $1.25
John runs a marathon (26.2 miles) in 4 hours. Determine how many miles he runs per hour if the proportional relationship is represented by 4y = 26.2x.
Answer Choices:
* 104.8 mph
* 6.55 mph
* 7 mph
* 0.15 mph
Answer Choices:
* 104.8 mph
* 6.55 mph
* 7 mph
* 0.15 mph
To determine the number of miles John runs per hour, we need to divide the total distance by the total time it took him.
Given: 4 hours = 26.2 miles
From the equation 4y = 26.2x, we can see that y represents the number of miles John runs in 4 hours, and x is the number of hours.
So, y = 26.2 miles
John runs 26.2 miles over the course of 4 hours, so to find how many miles he runs per hour, we need to divide the total distance by the total time:
miles per hour = 26.2 miles / 4 hours = 6.55 miles per hour
Therefore, John runs 6.55 miles per hour.
So, the correct answer is:
- 6.55 mph
Given: 4 hours = 26.2 miles
From the equation 4y = 26.2x, we can see that y represents the number of miles John runs in 4 hours, and x is the number of hours.
So, y = 26.2 miles
John runs 26.2 miles over the course of 4 hours, so to find how many miles he runs per hour, we need to divide the total distance by the total time:
miles per hour = 26.2 miles / 4 hours = 6.55 miles per hour
Therefore, John runs 6.55 miles per hour.
So, the correct answer is:
- 6.55 mph
The proportional relationship of 15.24 centimeters in 6 inches is represented by 6y = 15.24x. Determine the number of centimeters in 1 inch.(1 point)
Answer Choices:
* 91.44 centimeters
* 2.54 centimeters
* 0.39 centimeters
* 3 centimeters
Answer Choices:
* 91.44 centimeters
* 2.54 centimeters
* 0.39 centimeters
* 3 centimeters
To determine the number of centimeters in 1 inch, we can use the equation provided:
6y = 15.24x
Since the relationship is between 15.24 centimeters and 6 inches, x is the number of inches and y is the number of centimeters.
To find the number of centimeters in 1 inch, we plug in x = 1 into the equation and solve for y:
6y = 15.24(1)
6y = 15.24
y = 15.24 / 6
y = 2.54
Therefore, the number of centimeters in 1 inch is 2.54 centimeters.
So, the correct answer is:
- 2.54 centimeters
6y = 15.24x
Since the relationship is between 15.24 centimeters and 6 inches, x is the number of inches and y is the number of centimeters.
To find the number of centimeters in 1 inch, we plug in x = 1 into the equation and solve for y:
6y = 15.24(1)
6y = 15.24
y = 15.24 / 6
y = 2.54
Therefore, the number of centimeters in 1 inch is 2.54 centimeters.
So, the correct answer is:
- 2.54 centimeters
