1 answer:
Answer:
7/22
Step-by-step explanation:
Step 1: <u>Define/explain.</u>
To subtract fractions with different denominators, you must first find the least common denominator (LCM).
You can do this by listing the multiples of each denominator.
Step 2: <u>Solve.</u>
11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110
2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22
22 is the LCM.
Now, we change the fractions to where they both have denominators of 22.
**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**
Now, subtract as normal.
Step 3: <u>Conclude.</u>
Therefore, 9/11 - 1/2 = 7/22.

Answer:
$120
Step-by-step explanation:
The initial fee that was charged is the y-intercept of the equation that represents the situation given.
Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.
Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.
First, using two pairs, (105, 183) and (140, 204), find the slope (m):
m = ⅗
To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into .
Subtract 63 from each side
The initial fee of the company is $120.
