Answer: 125,000 BTUs
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs
So, the proportion is:
36 gallons / 4,500,000 BTUs
For 1 gallon
1 gallon / x BTUs
36/4,500,000 = 1/x
Solving for x:
x = 1 / (36/4,500,000)
x = 125,000 BTUs

Answer:
1/9
Step-by-step explanation:
(-3)^0 = 1
(-3)^2 = 9
so, 1/9
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
