Answer:
Step-by-step explanation:
50 dollars = ∉34
∉1 = Rs 150
Rs 382800 / 150 Rs per ∉  =  382800/150 ∉
=2552 ∉
50 dollars = ∉34          so 50/34 dollars = ∉
2552 ∉ × 50/34 dollar per ∉ =       in the units the ∉ cancel out
                                                          ∉ × dollar/∉    = dollars
(2552 × 50) / 34    = 3752.94 dollars     <------------------
Here is another way of looking at the answer...........
Rs 382800 × 1∉/150 Rs × 50 dollars/34 ∉ =              note how the units cancel
= 382800 × (1/150) × (50/34)                          Rs × ∉/Rs × dollars/∉ 
=  3,752.94 dollars                                     leaving only dollars in the numerator
 
        
             
        
        
        
Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒  x-y=-4
   2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
 
        
             
        
        
        
Answer:

So here we have (a⁵)², meaning we need to multiply the exponents to get a¹⁰ 
 
        
             
        
        
        
Answer:
thanks
Step-by-step explanation:
 
        
             
        
        
        
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3. 
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
