Answer:
n=B-q/q
Step-by-step explanation:
Well area is length time width and to do the opposite you have to divide. Just do 14 1/2 ÷ 4 1/3. If you use a calculator you would get 3.34615385, but all you pretty much need is 3.346. Your width is 3.346 and length is 4 1/2 or 4.5. Check by multiplying them you would get 14 1/2 or 14.5.
Hoped I helped!
Answer:
As x increases without bound, f(x) decreases without bound.
Step-by-step explanation:
i am pretty sure its At least x increases without bound, f(x) decreases without bound.
im not sure about the others but i think its only that one even tho its multiple choice, sorry if im wrong
$1.88 is our amount after the 380% is added!
$1.88 - 380%*x = x
Note, that when you are working with percents in a problem you need to convert the percent into a decimal value in order to properly work with it in an equation like the one above.
So, it will look like this:
$1.88 - 3.8x = x
Now onto explaining how I derived this equation in the first place, because it doesn't help you if you don't know how to do it yourself.
How a percent problem works is if you are taking some original price x, and increasing it by 380% you would take 380% of the item, and then adding it to the item. To take 380% of an item you would need to multiply the number by 380% (3.8). So, if you translate that into math it looks like this:
x + 380%*x = y
Y, in this case is $1.88. In other words it is the price AFTER you've added 380% to the cost. So I started to solve for x by subtracting 380%*x on both sides leaving us with this:
$1.88 - 3.8x = x
We need to solve the equation for x by adding 3.8x on both sides.
$1.88 = 3.8x + x
Combine like terms.
$1.88 = 4.8x
Divide both sides by 4.8.
$1.88/4.8 = x
So our original price is $1.88/4.8!
The question asks for the 380% * x part of the problem.
So we take our answer and multiply it by 3.8.
($1.88/4.8)*3.8 = $1.49 mark up!
