Answer:
SLOPE = -5
Step-by-step explanation:
Because that's what x is.
Each peach costs $0.56 and the equations used to solve that is
where x is the cost of 1 peach.
Step-by-step explanation:
Step 1:
It is given that all the peaches weigh the same and that 4 peaches weigh 1 pound.
Assume that each peach costs x.
So the cost for 4 peaches is given by 
Step 2:
The cost of 1 pound of peaches is given as $2.24.
1 pound of peaches
So 

So each peach costs $0.56.
Question 1)
Gwen has already burned 100 calories when Tristan and Keith started, and he continues to burn 10 calories per minute. The equation for Gwen is
y = 100 + 10x
Question 2)
`Tristan is burning 125 calories every 10 minutes. His burning calories rate is 12.5 calories per minute. The equation for Tristan is
y = 12.5x
Question 3)
Keith is burning 300 calories in 30 minutes. His rate per minute is 10 calories per minute. The equation for Keith is
y = 10x
The question is asking you to find the measure of YZ's arc.
The arc of a circle is found by finding the central angle. In this case, that's angle YCZ. Remember that a circle's total degrees is 360. Since the angle that you are trying to find is 16% of the circle, you need to find 16% of 360.
360*0.16 = 57.6
The measure of arc YZ is 57.6 degrees.
