Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000
5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.
So you all need to do is replace each letter by its value and do the calculus:
5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13
So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)
Hope this helps! :)
D is correct. Hope this helped.
Answer:
same
Step-by-step explanation:
same solution means same slope
Well convert 3 5/6 to 23/6 and 4 4/5 to 24/ 5
then find a multiple that both 5 and 6 have which is 30
23x5= 115 and 24x6= 144
so 115 x 144= 16560/30
16560/30 = 552 /1 so your answer is
552
