Step-by-step explanation:
cost of an egg= 900/100= Rs.9
Total cost = 100×9=Rs.900
when 8 eggs broken, the eggs remained to sell is 92(100-8)
Total sales = 10.50×92=Rs.966
profit = total cost-total sales
profit =966-900= Rs.66
profit percentage =profit/total sales×100%
66/966×100%=6.832%
Answer:
x = -1.
Step-by-step explanation:
√(x + 10) - 4 = x
√(x + 10) = x + 4
Squaring both sides:
x + 10 = x^2 + 8x + 16
x^2 + 8x - x + 6 = 0
x^2 + 7x + 6 = 0
(x + 6)(x + 1) = 0
<u>x = -6, -1.</u>
Check for any extraneous roots:
√(x + 10) - 4 = x
<u>Try x = -6:</u>
√(-6 + 10) - 4 = 2 - 4 = -2.
but we found x = -6 , so -6 is not a root.
<u>Try x = -1</u>:
√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.
