Maslowich

Answer:

430

Step-by-step explanation:

<u>Given :-</u>

  • By selling a watch on 400 and 460’. Loss and profit happened respectively.
  • The loss and profit are equal.

And we need to find out the CP .So ,

<u>Let :- </u>

  • CP be x
  • Profit and Lost be y .

<u>According to the Question :- </u>

:\implies 460 = x + y <em>( Profit)</em>

:\implies 400 = x - y <em>( Loss)</em>

<u>Adding both :- </u>

:\implies 460 + 400 = x + y + x - y

:\implies 860 = 2x

:\implies x = 860/2

:\implies x = 430

<u>Hence the Cost price of the watch is 430 .</u>

<span>Solve the system

9x = 27-9y
20x=71-9y

Let's use the "elimination through addition/subtraction method.
Multiply the first equation by -1 so as to obtain +9y:

-9x = -27 + 9y
</span><span>20x=  71-   9y
--------------------

Add these 2 equations together:

</span>-9x = -27 + 9y
20x=  71-   9y
--------------------
<span> 11x = 44

Solve this for x:  x = 44/11 = 4.

Now find y by subst. 4 for x in either of the original equations.

Using the second equation:    </span><span> 

</span>20x=71-9y
20(4) = 71 - 9y
80-71 = -9y
9 = -9y.  Then y = -1.

The solution set is (4,-1).

Chin canned a number of quart jars and a number of pint jars of tamoatoes from his garden a pint is 16 ounces and a quart us 32
natulia [17]
The total volume of the canned tomato sauce is equal to the sum of those canned in quart jars (32 ounces) and the number of pint jars (16 ounces). If we let p and q be the number of pints and quarts canned, the equation that would best represent the given is,
                                    32q + 16p = 1280
Simplifying the equation by dividing by 16 will give us the final answer of,
                                   2q + p = 80
