That expression is written like so:
(5 + d)/(12 - w)
Answer:
(1/2)s = 345
s = 690 (Maggie's savings balance)
Step-by-step explanation:
For any problem, word problem or otherwise, you start be reading and understanding the problem. You should specifically look for
- what you're being asked to find (what is the question to answer)
- the information you're given that is relevant to the question asked.
Here, you're asked to find a savings account balance. You're told that $345 is half that amount.
__
After you decide what you're looking for and the given relevant information, you use the problem statement and your personal knowledge to write one or more equations relating what you know to what you want to find.
A first step for doing this is to define any necessary variables. In this problem, we can use "s" for the original savings balance (in dollars). (I like to choose letters that remind me what they stand for. "x" or "y" can sometimes get mixed up. For a one-variable problem, it doesn't really matter what you call it. It is helpful to be clear about the units of measure of any variables. Confusion there can also lead to errors.)
The problem statement tells us that half the savings account amount is $345, so our equation is ...
(1/2)s = 345
__
The "one step" required to solve this so to multiply both sides of the equation by 2.
s = 690
Maggie had $690 in her savings account before she bought the computer.

Answer:
Step-by-step explanation:
The Bessel function or order zero of the first kind may be defined by the solution - to Bessel's differential equation - which is a finite value at the origin X=0 for positive or negative whole numbers (integers) or positive alpha (α) values.
Answer:
Please Explain
Step-by-step explanation:
13. A school is planning an excursion for all of their students to see the
penguins on Phillip Island. They find a company who can provide
two different types of coaches for the trip: one that holds 34
passengers and one that holds 51 passengers. The coach company
has 8 of the smaller coaches and 4 larger coaches available.
The hire cost $500 for a smaller coach and $700 for a larger coach.
If there are 374 students and teachers going on the trip,
determine the minimum total cost for the coach hire.
