In 75 minutes you travelled 30 kilometers, so the rate is 30/75=0.4km/minute

another way is to use the two points to find the slope: m=(30-0)/(75-0)=0.4

Answer:

Option B is correct.

Unit rate = 0.40 km/min

Step-by-step explanation:

Given : A graph with a line running through coordinates (0,0) and coordinates (75, 30).

Here, y represents the distance traveled in km and x represents the number of minutes.

Find the slope of the line:

Slope(m)= \frac{change in y-axis}{change in x-axis} = \frac{y_2-y_1}{x_2-x_1}

Given points: (0, 0) and (75, 30)

then;

m = \frac{30-0}{75-0} = \frac{30}{75} =0.40 km/min

Since, unit rate is also the slope of the graph.

Therefore, unit rate(in km/min) = 0.40 km/min

What is the elimination of 20x+5y=120 and 10x+7.5=80
Grace [21]
20x+5y=120
10x+7.5y=80    multiply this one by 2
___________

20x+5y=120
20x+15y=160   subtract 

___________

        -10y=-40    divide both sides by -10 
____________

             y=4         

20x+5(4)=120   plug 4 in for y in the first equation 
20x+20=120     multiply 
20x=100           subtract 
x=5                   divide to find x

The jars of paint in the art room have different amounts of paint. The green paint jar is 4/8 full. The purple paint jar is 4/6
Novay_Z [31]
4/8 is less full because the 6th fraction is more than the 8th and there is the same amount of pieces.
