X + y = 180
Y = wheat, x = oats
Y = x + 20. In the 1st equation, get y by itself getting y = 180 - x.
So 180 - x = x + 20. Subtract x on both sides to get 180 - 2x is 20. Subtract 180 to both sides is -2x = -160. Divide -2 to both sides is x = 80. So 80 + 20 is 100 wheat, and 80 oats of acres.
Answer:
Ratio between balances will be:

Where;
x = deposit
%i = interest rate annual
n = years
Step-by-step explanation:
Lets say first deposit is x$ for both investment and annual interest rate for both investment are %i. Also, they stayed under i interest in n years:
Total balance for simple interest is:

How ever total balance for compound interest is:

28 cups is 1.75 gallons or 1 and 3/4 gallon
This function to find a discounted price of a computer you must knowork how to find a sale price. To do this take the cost of the item on sale and multiply it be the percent that you will pay. I this case the computer is 10% off. Which means you will pay 90%. To show this as a function: P(x)=x*0.90 or P(x)=0.90x. Hope this helped.
