Answer:
C
Step-by-step explanation:
$6500 is a one time purchase so there is no variable attached.
$550 and $900 per week is reoccurring so there will be a variable attached.
Since $900 is what she is making each week, this will be separate from her costs (can eliminate D).
To make a profit, her amount earned will need to be greater than her expenses, so the answer is C.
Well, first I split it up into two different equations:
6-4=2
5/8-2/9=.4027
Then, added the two: 2.4027
Answer:
The answer is 0.46947

Step-by-step explanation:
Givens
r = 14 miles / hour
Problem
Convert to feet per second.
Solution
Later on, you will learn how to solve these kinds of conversion problems using a method called Unit Analysis. Since you likely have not been taught this method, will just use proportions.
1 mile = 5280 feet
14 miles = x Cross multiply
x = 14 * 5280 Simplify
x = 73920 feet
1 hour = 3600 seconds
Answer
r = 73920 feet / 3600 seconds
r = 20.533 feet / secpmd
Answer:
Step-by-step explanation:
Let the numbers be x , y
Sum of two numers = -7
x + y = -7------------(I)
Two times the first number equals 4 the second number.
2x = 4y ----------(II)
Divide both sides by 2
x = 2y
Subtitute x = 2y in equation (I)
2y + y = -7
3y = -7
y = -7/3
Plugin y = -7/3 in equation (II)
