Answer:
A = 48
Step-by-step explanation:
In this equation, we can factor out the expression
. If we do so, the expression becomes:
![(\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B7%7D%29%5Ex%28%28%5Cfrac%7B1%7D%7B7%7D%29%5E%7B-2%7D%20-%201%29)
We can simplify to get:
![(\frac{1}{7} )^x(49 - 1)](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B7%7D%20%29%5Ex%2849%20-%201%29)
and get:
![48*(\frac{1}{7})^x](https://tex.z-dn.net/?f=48%2A%28%5Cfrac%7B1%7D%7B7%7D%29%5Ex)
Therefore, A = 48
Answer:
C.) 63
Step-by-step explanation:
You know what you insisted on me answering, so I'll answer here.
35 ÷ 5 = 7
7 x 9 = 63
#7:
<span>Subtract </span>y<span> from both sides:
</span>-4x=6-y
Divide both sides by -4:
Answer:
x= -6-y/4
#7 part 2:
Add <span>y</span><span> to both sides:
</span>-5x=21+y
Divide both sides by -5:
Answer: x=-21+y/5
hope i helped!
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
