Answer: 2 : 50 pm 
Step-by-step explanation:
If Jan took a break at 3:05 pm and she had been jumping rope for 15 minutes before that, to find the time she started jumping rope, subtract 15 from the current time:
= 3:05 - 15
= 2:50 pm 
<em>Jan started jumping rope at 2 : 50 pm </em>

Answer:
y = (3/4)x + 2
Step-by-step explanation:
Slope-intercept form is y=mx+b where (x, y) is a point on the linear graph, m is the slope (rise/run), and b is the y-intercept (the y-value at which the graph passes through the y-axis). 
Looking at the graph, we can see that the point at which the line crosses the y-axis is (0, 2) which makes it the y-intercept. Thus, the b in the slope-intercept form is 2. 
Next, we are looking for the slope of the line. To do this, we can calculate the rise/run of the line by choosing to points on it. Since we already have the point (0, 2), we just need one more. 
For example, the point (-4, -1) can be used. The slope can be found by ((y-y)/(x-x)) in which the first y and x values correspond with the first point and that of the second correspond with the second set. So in this case, m = (2-(-1))/(0-(-4)) = 3/4
Plugging in the calculated m and b value in the slope intercept equation, we get y = (3/4)x + 2
 
        
                    
             
        
        
        
Answer:
11
Step-by-step explanation:
5x+15+20=90
5x+35=90
-35 from both sides
5x=55
divide both sides by 5
x=11
 
        
                    
             
        
        
        
Answer:
The width is 
Step-by-step explanation:
The perimeter of the rectangular yoga mat can be found using the formula;
 .
.
 .
.
It was given that the width of the mat is eight less than half the length.

We put equation (2) into equation (1) to get;
 .
.
 .
.
 .
.

Divide both sides by 3;

We put  into equation 2 to get;
 into equation 2 to get;
