Answer:
The absolute value of -3 1/2 is 3 1/2.
Step-by-step explanation:
The absolute value of a number is its distance from 0.
In this case the absolute value of -3 1/2 is 3 1/2.
Another way to write is I-3 1/2I
Using the absolute value bar

Answer:
 Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
Explanation:
 Distance traveled by a body = Velocity of the body * Time taken by the body
 Here velocity of Sierra =  2x miles per hour
 Time taken by Sierra = h hours.
 Distance traveled by Sierra = 2x * h = 2xh
 So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
                                               
 
        
             
        
        
        
Step-by-step explanation:
x = 145°
we don't even need the upper parallel line with the 35° angle.
it is simply based on the fact that the angles on both sides of 2 intersecting lines have to be the same (just left-right mirrored).
 
        
             
        
        
        
Letter D
A = 135°
B = 30°
cosAcosB - sinAsinB = cos(A+B)
cos(135°+30°)
cos(165°)
