Answer:
21 & 11
Step-by-step explanation:
Let x = first number and y = second number. We need to find the values of x and y, so we need to set up a system of linear equations. The first equation would be x + y = 32 because x and y add up to 32. Then the second equation would be x - y = 10 to represent that the two numbers have a difference of 10. Solving by elimination, we add and get 2x = 42, so x = 21. Then substitute 21 for x in either one of the equations to get y = 11.

Answer:
Step-by-step explanation:
After the 440 pennies are added, the bank is 3/5 full. It started out 1/10 full, so
3/5 - 1/10 is the amount of space in the bank that the 440 pennies took up, or
1/2. Use proportions to solve this, with number of pennies on the top and the fraction of the bank that is filled on the bottom:
where x is the number of pennies (our unknown) that it will take to fill the bank (1). Cross multiply to get
so x = 880
