I need to create a word problem that requires equations to solve it!! HELP!!?

Question

I need to create a word problem that would require the use of equations to solve the problem, and write an "answer key" which explains the solution to the problem.

I have no idea how to do this can anyone help!!
Thanks Ashley~

Answer 1

first off all u must think of the asic idea of the solution.
then decide what is the required from this problem
then determine what information should be given to solve this problem
make sure everything is alright and try to solve it
start to write the problem in words and make sure its clear and only has one meaning
solve the problem again
and now u r ready to test someone

Answer 2

Well, start out by deciding what kind of equations or problem you want it to be. Decide based on what you've been learning lately...what level of math are you in?


Then think of a situation that might require equations that look like the ones you know how to use---I'll use linear equations as an example.

You can set up a linear situation using an airplane. Since you can find the equation of a line if you have two points, you can say something like

"Bob was flying his plane over a city. After half his trip, Bob was over a point five blocks east of his starting point and two blocks north. "

Then pick some kind of question that would make the person have to find the linear equation y=(2/5)x and go on from there.

I can help you better if I know what type of stuff you've been learning in school...

Answer 3

Here's 1 example:

"A fish is caught and is weighed, but is too heavy to be weighed in one piece, so it is cut into 3 parts. The main part of the body weighs 4Kg, the head weighs half of the main body plus the weight of the tail, and the tail weighs half of the head. What is the total weight of the fish?"

I'll solve it just so it can be seen what steps are involved.

The head can be written as:

H = 1/2 B + T

The tail can be written as:

T = 1/2 H

We already know that the main body is 4Kg, so we can replace it into the first equation.

H = 1/2(4) + T

H = 2 + T we can rearrange this to make T the subject of the formula

T = H - 2 but also T = 1/2 H

So we can put the 2 equations equal to each other:

H - 2 = 1/2H

H - 1/2H = 2

1/2H = 2

H = 4Kg

Putting this into the first equation (T = H - 2) we find that the tail = 2Kg

So the total weight of the fish = 4 + 4 + 2 = 10Kg


Hope this helps!

Answer 4

Question:

There are 40 kids in the classroom.
There are 3 times as many boys as there are girls.
How many boys and girls are there?

KEY:

x=boys
y=girls
z=total kids (a known constant here, not a variable)

Hence we know:
x + y = 40 (a known, the total number of kids)
x = 3y (a known also)

From substitution:
3y + y = 40
4y = 40
y = 10

AND resubstituting our known value back into orig. equation:
x + y =40
x + 10 = 40
x = 30

30 boys, 10 girls.

Simple, but effective. Outlines all the basic procedures for problem solving in algebra.

Identify knowns and unknowns. Establish relationships between them. For any "x" number of unknowns, if you can establish "x" number of known relationships, you can usually get a unique solution not involving any variables.

Hope this helps

Answer 5

I’ve paid 25 tugriks for a cap and a scarf, the cap being 5 tugriks more than the scarf; what is the price of each?
So x+y=25 and x-5=y; x=15, y=10;

Answer 6

why dont you attempt to do the vertical distance lined bny a ball that's thrown at a undeniable speed as a functon of time s = ut -a million/2gt^2 you will see for each s which you're taking there will be 2 cases, which shows it occupies the comparable top at 2 distinct cases , how ? its glaring because of the fact once you throw it up it reaches a undeniable top and whilst it truly is falling down it crosses the comparable top it truly is a stable examplke of making use of quadratics you may try the comparable way projectile action yet im uncertain which grade you're in all the terrific
