<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given that the price of gas started at $2.25 and increased at a rate of 4% per year.
We are to write a function which models this situation using numerical values of A and r into the expression.
A = $2.25
r = 4%
Assuming x to be the time in years, the function would be:

Answer:
1000 Grams : 1 Kilogram or 1 Kilogram : 1000 Grams
Step-by-step explanation:
In the metric system the value of a kilogram is solved like:
When converting from grams to kilograms, we solve it like:
Let's take for example:
2 KG is how many grams?
We use the grams to kilograms formula like so:
Then we end up with:
g = 2000
The combined distance between CD and DE is CE, so...
2x+4 + 6 = x+14 Simplify like terms..
2x + 10 = x + 14 Subtract x from both sides..
x + 10 = 14 Subtract 10 from both sides...
<h2><u><em>
x = 4</em></u></h2>
Proof: 2 (4) + 4 + 6 = 4 + 14
8 + 10 = 18
<em> Check</em>
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2
You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.
Hope this Helps! :)
The answer is choice C
Plane D(choice C) because choice a and b are not lines(one letter cannot be a line and PBC and not connected). It's not d because e isn't a point
