X = bessie and y = betty
x + y = 1464
y = 2x - 375
x + 2x - 375 = 1464
3x - 375 = 1464
3x = 1464 + 375
3x = 1839
x = 1839/3
x = 613 <== Bessie gave 613 gallons
y = 2x - 375
y = 2(613) - 375
y = 1226 - 375
y = 851 <== Betty gave 851 gallons
Yes your answer would be correct! :)
First step is parentheses so subtract 1/4 from 1
(1-1/4) = (4/4 - 1/4) = (3/4)
After parentheses we perform exponent operations
(3/4)^2 = (3^2/4^2) = (9/16)
Finally, after exponent operations we perform multiplications
(1/3)*(9/16) = (3/16)
