Correct me if I’m wrong plz
        
             
        
        
        
X + y = 46
x = y + 12
y + 12 + y = 46
2y + 12 = 46
2y = 46 - 12
2y = 34
y = 34/2
y = 17
x = y + 12
x = 17 + 12
x = 29
so ur 2 numbers are : 29 and 17
        
                    
             
        
        
        
Answer:
t = 139/490 + sqrt(75671)/490 or t = 139/490 - sqrt(75671)/490
Step-by-step explanation:
Solve for t:
4.9 t^2 - 2.78 t - 1.15 = 0
4.9 t^2 - 2.78 t - 1.15 = (49 t^2)/10 - (139 t)/50 - 23/20:
(49 t^2)/10 - (139 t)/50 - 23/20 = 0
Multiply both sides by 10/49:
t^2 - (139 t)/245 - 23/98 = 0
Add 23/98 to both sides:
t^2 - (139 t)/245 = 23/98
Add 19321/240100 to both sides:
t^2 - (139 t)/245 + 19321/240100 = 75671/240100
Write the left hand side as a square:
(t - 139/490)^2 = 75671/240100
Take the square root of both sides:
t - 139/490 = sqrt(75671)/490 or t - 139/490 = -sqrt(75671)/490
Add 139/490 to both sides:
t = 139/490 + sqrt(75671)/490 or t - 139/490 = -sqrt(75671)/490
Add 139/490 to both sides:
Answer: t = 139/490 + sqrt(75671)/490 or t = 139/490 - sqrt(75671)/490
 
        
             
        
        
        
Answer:
Okay. So first you add 22+28=50.  Then subtract 1,738-50=1,688. Then divide 1,688 by 2 witch should give you an answer of 844 miles each day.              Hope it helped!
