Answer:
C) 
Step-by-step explanation:
Answer:
Cost of 1 kg apple = a = RS 102 (Approx.)
Cost of 1 kg orange = b = RS 61 (Approx.)
Step-by-step explanation:
Assume;
Cost of 1 kg apple = a
Cost of 1 kg orange = b
So,
2a + 6b = 570 ....... Eq1
and
3a = 5b..........Eq2
From eq 2
3a = 5b
a = 5b / 3
So,
2a + 6b = 570
2(5b/3) + 6b = 570
b = 61.07
Cost of 1 kg orange = b = RS 61 (Approx.)
a = 5b / 3
a = 5(61) / 3
Cost of 1 kg apple = a = RS 102 (Approx.)
Answer:
5/8, -5/8
Step-by-step explanation:
64x^2 = 25
divide both sides by 64
x^2 = 25/64
take the square root of both sides, and the negative square roots
