Answer:
Step-by-step explanation:
Start: 10 gallons
Loss: 1.75 per hour --> -1.75 gallons
After two hours 10+2(-1.75)=10-3.5=6.5 gallons left
After t hours 10+t(-1.75)=10-1.75t gallons left
x = 2
note that 4096 = , then
=
Since bases on both sides are equal, both 8 , then equate the exponents
2x = 4 ( divide both sides by 2 )
