1/5 is the answer to your question
Answer:
Part A: 12.5 cm
Part B: 0.8 km
Step-by-step explanation:
Map scale problems can be solved with proportions.
Part A
5 cm / 2 km = x cm / 5 km
5/2 = x/5
2x = 25
x = 12.5
Answer: 12.5 cm
Part B
5 cm / 2 km = 2 cm / x km
5/2 = 2/x
5x = 4
x = 4/5
x = 0.8
Answer: 0.8 km
Associative property of addition.
This means that no matter where you put the parenthesis, you will get the same solution.
Hope this helps!
Answer:
For employee 1 = 2.5
For employee 2 = 8.6
For employee 3 = 4.4
For employee 4 = 10
For employee 5 = 24
Step-by-step explanation:
number of hour worked= H
total money earned =T
earning per hour =M
we have the following relations:
H =T/M
M =T/H
For employee 1 we have:
T=23.75$
M =9.50$
We calculate H by using the above equations, so we have:
H =23.75/9.50= 2.5
For employee 2 we have:
T=28.38 $
H =3.3
We calculate M by using the above equations, so we have:
M =28.38/3.3 =8.6
For employee 3 we have:
T=38.50$
M =8.75$
We calculate H by using the above equations, so we have:
H =38.50/8.75= 4.4
For employee 4 we have:
T=55 $
H =5.5
We calculate M by using the above equations, so we have:
M =55/5.5=10
For employee 5 we have:
T =60 $
H =2.5
We calculate M by using the above equations, so we have:
M =60/2.5 = 24
<span>I believe you MEANT 8/(x^2-25)+9/(x-5) Parentheses in this format are important...the way you typed it means (8/x^2)-25+(9/x)-5 which I doubt you mean. Anyway.
If you factor the first denominator you will see that it is equal to (x+5)(x-5). Division by zero has no meaning so x cannot equal -5 or 5.
If we multiply the second fraction by (x+5) we will have a common denominator of (x^2-25) for the entire equation leaving us with:
(8+9x+45)/(x^2-25)
(9x+53)/(x^2-25)
The second problem is worked in exactly the same way, notice that there is no "solution" as there is no equal sign. This is an "expression" not an "equation".</span>
