Answer:
(2,-3)
Step-by-step explanation:
I used substitution and rearranged the second equation to y=-2x+1. Then I replaced the y in the first equation with -2x+1. So, I got 3x-5(-2x+1)=21. When you solve that you get 13x=26 or x=2. Then you replace x with 2 in either equation and end up with y=-3.
 
        
                    
             
        
        
        
Answer:
The answer is
<h2>376 cm²</h2>
Step-by-step explanation:
Since the rectangular box is a cuboid, 
Total surface area of a cuboid is given by
<h3>2( lw + wh + lh)</h3>
Where 
l is the length
w is the width
h is the height
From the question
l = 10 cm
w = 8cm 
h = 6cm
Substitute the values into the above formula
That's
Total surface area of the rectangular box is
2 [ (10)(8) + (8)(6) + (10)(6) ]
2 [ 80 + 48 + 60 ]
2( 188)
We have the final answer as
<h3>Total surface area = 376 cm²</h3>
Hope this helps you
 
        
             
        
        
        
Answer:
Can't answer because we don't know the distance between start position and Middelburg, as well as the number of stops along the way
Step-by-step explanation:
 
        
             
        
        
        
Well 5 1/4 hours is 5 hours and 15 minutes and 2/3 of 5 hours and 15 minutes or 315(5*60+15) is 210
hope it helped
