Answer:
43.71428571
Step-by-step explanation:
First, convert 7 2/7 into an improper fraction: 51/7
Second, multiply 51/7 by 5: 255/7
Third, add 255/7 and 51/7 to get 306/7
306/7 = 43.71428571
1.95 + 1.09 = 3.04 so you will spend $3.04 then 5 - 3.04 = $1.96
84, 000, 108 is the answer.
3^x = 729
log(3^x) = log(729)
xlog(3) = log(729)
x = log(729)/log(3)
x = 6
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
