The ending balance and outstanding checks are both negative in the book of accounting. The positive item she had is only the outstanding deposits. We let x be he amount she will need in order to pay for her telephone bill and that,
148.1 = x + 412.39 - (546.78 + 872.63)
From the equation above, the value of x is 1155.12. Thus, she needs an additional amount of approximately $1155.12 to pay for her telephone bill.
In the year 2009 there were 3500 birds on an island. If the bird population is declining 2.2% per year it means that in the year 2014 we will have 3500*
= 3131.57 birds.
The best prediction is that in the year 2014 the bird population will be 3132.
The length should be 31 feet and 3 inches
Explanation:
You use a proportion to find the length
Certain to happen, because the whole bag is made of primary colors
and the probability is 1, but not sure about the second one
The
Least Common Denominator (also called
LCD) is very important to
working with rational expressions. The process we use to find the LCD of the exponents is based
on the process used to find the LCD of intergers. For instance, to find the LCD of 8 and 6 you need:
1. Consider multiples of the larger number
8, 16, 24,...
2. 24 is the first multiple of 8 that is also divisible by 6
3. Then 24 is our Solution.
To answer the question regarding expressions with exponents let's take an example:
Find the LCD of
:
1. 12 is the LCD of 4 and 6
2. Use all variables with highest exponents on each variable, then
3. Finally,
solutions is:
