The equation given in the question has two unknown variables in the form of "x" and "y". The exact value of "x" and "y" cannot be determined as two equations are needed to get to the exact values of "x" and "y". This equation can definitely be used to show the way for determining the values of "x" in terms of "y"and the value of "y" in terms of "x". Now let us check the equation given.
2x - 5y = - 15
2x = 5y - 15
2x = 5(y - 3)
x = [5(y - 3)]/2
Similarly the way the value of y can be determined in terms of "x" can also be shown.
2x - 5y = - 15
-5y = - 2x - 15
-5y = -(2x + 15)
5y = 2x + 15
y = (2x +15)/5
= (2x/5) + (15/5)
= (2x/5) + 3
So the final value of x is [5(y -3)]/2 and the value of y is (2x/5) + 3.
Answer:
profit : RS 150 and profit % : 3%
Step-by-step explanation:
for profit 10% for loss 4%
s.p will be 2750. s.p will be 2400
Total s.p : 2750 +2400. total s.p : 5150
profit = s.p-c.p. profit%=?
=5150-5000. profit = p /c.p × 100
=150 = 150/5000×100
= 3%
Where are the numbers so that people can help you
The answer would be 53. This can be found by add 127 twice (xy and uz) and subtracting it from 360. This would give you 106 and you would divide it by 2 for the 2 angles left and get the answer.
Answer:
Step-by-step explanation:
14 - If you add all she spent such as (1.95,30.00,7.50) then add it to what she has left over. You get $77.65
16- (63 x 2)+63+6=195
