Answer:
Therefore,
Jana bikes 18 miles in one hour.
Step-by-step explanation:
Given:
Jana bikes,
15 miles ---------------> in 50 minutes
To Find:
How many miles ------------------> in 1 hour = 60 minutes
Solution:
Let 'x' miles Jana Bikes in 1 hour or 60 minutes
As, 1 hour = 60 minutes
The Ratio of Equation will be

Cross Multiplying we get

Therefore,
Jana bikes 18 miles in one hour.
Graph is incorrect.
Find points (x,y)
If x=#, what does y=?
Example:
Y=5x+4
Y=5•0+4
Y=0+4
Y=4
Points:
(0,4)
(-1,1)
(-2,-6)
Also, only draw the line in areas where x≤0
Meaning nothing should be on the right half of the square.
The range means what Y values are possible?
When draw properly, with nothing on the right half, the highest Y value will be 4.
So, the range is y≤4
49/60 - 3/20 = (49 - 3(3))/60 = (49 - 9)/60 = 40/60 = 4/6 = 2/3

Answer:
2/3
Answer: i think 4
Step-by-step explanation:
Answer: The system of equations are;
a + b = 9 ———(1)
a + 3b = 23———(2)
Step-by-step Explanation: The variables used here are a and b. Where a represents the number of free throws and b represents the number of three-pointers.
From equation (1), what we have is the total number of shots he has taken altogether which is 9 shots in all. All 9 shots are an addition of free throws and three pointers (that is a + b).
In equation (2), what we have is the points obtainable times the number of shots taken (for each shot). This means if a is a free throw, then 1 times a is equal to number of free throws times 1. Similarly, if b is a three-point throw, then 3 times b is equal to the number of three pointers thrown times 3.
The solution to the equation above gives us,
a = 2 and b = 7
