Answer:
You are 25
Step-by-step explanation:
This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.
We proceed in a stepwise manner
let say what I have is x
1. Subtract 5 from me
(x-5)
2. Then add 2
(x-5)+2
3. If you subtract 10
(x-5)+2-10
4. And then add 3
(x-5)+2-10+3
5. you get 15
(x-5)+2-10+3=15
what am I is the question we need to answer, we do this by solving for x
x-5+2-10+3=15
x-15+5=15
x-10=15
x=15+10
x=25
Since the price of the cantaloupes is unknown, it will have to represented by a variable. Let's use x.
If Jackson starts with $25 and buys 5 cantaloupes of an unknown price, this subtracts 5 times the amount of 1 cantaloupe (which is x) from that $25.
This is shown as 25 - 5x.
After spending that money, he has $2.50 left over.
This means 25 - 5x = 2.50.
Now you just need to solve this by first isolating the variable.
First, subtract 25 from both sides.
25 - 5x - 25 = -5x
2.50 - 25 = -22.5
Then, divide both sides by -5. It's -5 since 5 is the coefficient and it's negative, so -5.
-5x / -5 = x
-22.5 / -5 = 4.5
This means x = 4.5.
And if x is 4.5, then that means the cost of 1 cantaloupe is $4.50.
0.15 x 10^3 just means that you will move 3 decimal places to the right.
So we get 150
<span>((x+deltaX)^2+x+deltaX-(x^2+x))/deltaX = (x^2 + 2x delta x + (delta x)^2 + x + delta x - x^2 - x) / delta x = delta x (2x + delta x + 1) / delta x = 2x + delta x + 1
Therefore, </span>Lim as x tends to 0 of <span>((x + delta X)^2 + x + deltaX - (x^2 + x)) / deltaX</span> = 1 + delta x
