Do as the apples goes up in 4s
3 7 11 the goes 3 +4 = 7, 7+4 = 11
and Sees goes up in 40's
30 70 110
and rate of change is
its 40/4 or 10/1 (that's the first one)
Answer:
1) Already in scientific notation
2) 2 x 10^5
3) 3 x 10^5
4) 1.5 x 10^5
Distributive property of this number is 3(24+15).
In mathematics, the distributive property of binary operations generalizes the distributive law, which asserts that the equality is always true in elementary algebra. For example, in elementary arithmetic, one has One says that multiplication distributes over addition.
In distributive property the form of the equation is a(b+c).
We know that in 72 and 45.
Both are divided by 3 and 9.
So we can use any one of this number.
So in the distributional form.
It will be ,
= 3(24+15).

$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!
