class a folds 160 fewer paper cranes than class b and 2/3 as many paper cranes as classsc.class b folds 92 more paper cranes than class c. how many paper cranes does class b fold

Answers

First, set up a system of equations:

a=b-160

a=2/3c

b=c+92

Then, pick a variable to solve for. I'll start with c.

So, we know that a=b-160 and b=c+92. That means the first equation could be written as a=(c+92)-160. Which simplifies to a=c-68, and a=2/3c, so really 2/3c=c-68. Simplify to 68=1/3c. to get rid of the fraction, multiply both sides by 3.

c=204.

Plug that into the other two equations,

a=2/3(204)

a=136

and

b=(204)+92

b=296

Train A arrives at the train station every 30 minutes, and Train B arrives every 40 minutes. Both are at the train station right now. In how many minutes will both be at the train station again?

Answers

in 40 minutes the both 2 trains will arrive

You're looking for the smallest number that's a multiple of both 30 and 40.
If you've learned about "Least Common Multiple" by now, you'll be happy
to know that that's exactly what this is, (because when you were learning it,
you wondered what in the world you could ever use it for). Well here you are.

The least common multiple of 30 and 40 is 120.
That's the 4th multiple of 30 and the 3rd multiple of 40.

If the trains are both in the station right now, then the next time they'll
both be here together will be 2 hours (120 minutes) from now.

And let me say in conclusion that when you ask for help with
a multiple-choice question, you must also post the choices that
you have. It's not fair to the helper if he doesn't know the choices.

18= 3/4d + 6
I keep getting that d=9 but it doesn't check right plz help

Answers

18 = 3/4d + 6

First, we can start out by making our goal to get the variable (d) by itself on one side. Let's begin by simplifying the fraction and the variable with each other.
$18 = (3d)/(4)$

Second, we can now start our journey to get the variable by itself. Subtract 6 from each side.
$18 - 6 = (3d)/(4)$

Third, let's subtract 18 - 6 to get 12.
$12 = (3d)/(4)$

Fourth, let's continue by multiplying both sides by 4.
$12 * 4 = 3d$

Fifth, we can now multiply 12 times 4 to get 48. This can be done by using a calculator, etc.
$48 = 3d$

Sixth, we can divide each side by 3. We officially got the variable (d) by itself, so our goal is completed and all we need to do is simplify our fraction we just got.
$(48)/(3) = d$

Seventh, our last step is to simplify our fraction. In simpler words, what multiples with 3 to equal 48? (3 times 16 = 48), so 48 is our answer. We can also switch sides.
$d = 16$

Answer: $\fbox {d = 16}$
