To determine the unit rate for 1 bag of chips, we need to find the value of y when x = 1 in the equation 5y = $6.25x.
Substitute x = 1 into the equation:
5y = $6.25(1)
5y = $6.25
Divide both sides of the equation by 5:
y = $6.25/5
y = $1.25
Therefore, the unit rate for 1 bag of chips is $1.25.
The correct answer is D. $1.25.
Determine the unit rate for 1 bag of chips if 5 bags cost $6.25; the proportional relationship is described by 5y=$6.25x
A. $31.25
B. $1
C. $0.80
D. $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.
6.55 mph
0.15 mph
104.8 mph
7 mph
6.55 mph
0.15 mph
104.8 mph
7 mph
To determine how many miles John runs per hour, we need to find the value of y when x = 1 in the equation 4y = 26.2x.
Substitute x = 1 into the equation:
4y = 26.2(1)
4y = 26.2
Divide both sides of the equation by 4:
y = 26.2/4
y = 6.55
Therefore, John runs at a speed of 6.55 miles per hour.
The correct answer is 6.55 mph.
Substitute x = 1 into the equation:
4y = 26.2(1)
4y = 26.2
Divide both sides of the equation by 4:
y = 26.2/4
y = 6.55
Therefore, John runs at a speed of 6.55 miles per hour.
The correct answer is 6.55 mph.
The proportional relationship 15.24 centimeters in 6 inches is represented by 6y=15.24x. Determine the number of centimeters in 1 inch.
To determine the number of centimeters in 1 inch, we need to find the value of y when x = 1 in the equation 6y = 15.24x.
Substitute x = 1 into the equation:
6y = 15.24(1)
6y = 15.24
Divide both sides of the equation by 6:
y = 15.24/6
y = 2.54
Therefore, there are 2.54 centimeters in 1 inch.
The correct answer is 2.54 centimeters.
Substitute x = 1 into the equation:
6y = 15.24(1)
6y = 15.24
Divide both sides of the equation by 6:
y = 15.24/6
y = 2.54
Therefore, there are 2.54 centimeters in 1 inch.
The correct answer is 2.54 centimeters.
