First start by adding them to find how many total marbles there are
10+40=50 there are 50 marbles and 10 of them are white
10 is 20% of 50 so 20% of the marbles are white
I hope I've helped!
Since the 3 and 7 have 21 as a common multiple you can divide 21 by the denominator of each term and then multiply it by the numerator which get you while numbers
Answer:
x = 12.29
Step-by-step explanation:
present value of the claim = x² / (1 + 2%)¹⁵ = 0.743x²
present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02³ + x/1.02⁴ + x/1.02⁵ + x/1.02⁶ + x/1.02⁷ + x/1.02⁸ + x/1.02⁹ = x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x = 9.1323x
0.743x² = 9.1323x
x² / x = 9.1323 / 0.743
x = 12.29
Hello!
Multiply both sides by 16
36x < -x
Add x to both sides
37x < 0
Divide both sides by 37
x < 0
The answer is x < 0 or any number less than 0
Hope this helps!
