Answer: The company currently has 17 employees
Step-by-step explanation:
Let X represent the number of current employees in the company
From the first information, it can be expressed mathematically as
X + 3 ≥ 20
X ≥ 20 - 3
X ≥ 17
From the second information, it can be expressed mathematically as
X - 3 < 15
X < 15 + 3
X < 18
From the above solutions, it can be deduced that
17 ≤ X < 18
The only number that fulfils this criteria is 17.
Therefore, X = 17
If you have six boys and fifteen girls, the ratio in the form of a fraction is 6/15.
To solve this we are going to use the simple interest formula:
where
is the final amount.
is the initial investment.
is the interest rate in decimal form.
is the time in years.
Investment A. We know that the initial investment is $10,000, so
. We also know that the number of years is 5, so
. To convert the interest rate to decimal form, we are going to divide the rate by 100%
Lets replace those values in our formula to find
:
Investment B. ,
, and
.
We can conclude that
investment A will be worth than investment B at the end of the investment period.
Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
<u>+5 +5</u>
2a=a+1
Now, subtract a on both sides.
2a=a+1
<u>-a -a</u>
a=1
Hope this helps you out!!!! Have an amazing day :3
