10 pennies...
x + y = 20 3.1x + 2.5y = 61.16 so from the first equation move the y to the other side x = -y + 20 Substitute into the second equation 3.1(-y + 20) + 2.5y = 61.16 -3.1y + 62 + 2.5y = 61.16 -.6y = -.84 y = 14 so x will be 6
100 pennies = 1 British Pound 2,000 pennies = 20 British Pounds
Yes, the mass of 10 pennies is equal to the mass of 10 times one penny. This is because mass is additive, meaning that the total mass of multiple objects is the sum of their individual masses. Therefore, 10 pennies will have the same mass as 10 multiplied by the mass of one penny.
