They are not the same, but they do have there similarities.

Answer:

So I have my own way of thinking:

So lets say a 25% increase of 60.

First what I would do is 25% x 60 = 15. THEN MAKE SURE YOU DON"T FORGET THIS STEP. You will have to do 60 + 15 = 75.

So that is for increase, you can do this with any numbers :).

So now lets say 25% decrease of 60.

First what I would do is 25% x 60 = 15 and then do 60 - 15 = 45. (Since we are decreasing)

So that is for the decrease, you can do this with any numbers :).

I HOPE THIS HELPS!!!!

60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles

part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles

total is 180mi+140mi=320miles

the product of two consecutive positive even integers is 14 more than their sum. Set up an equation that can
alexandr1967 [171]

Required equation to determine two consecutive even number is x^{2}-16=0 and required numbers are 4 and 6.

<u>Solution:</u>

Given that product of two consecutive positive integer is 14 more that their sum.  Need to create the equation and solve it to get two numbers.

Let’s assume first even number be represented by x.

So second consecutive even number will be x + 2  

Sum of two consecutive number = (x) + (x + 2)

\Rightarrow Sum of two consecutive number = 2x + 2

Product of two consecutive number = (x) \times(x+2)=x^{2}+2 x

Product of two consecutive number is 14 more that sum of two consecutive numbers, so if we subtract 14 from product, we will get sum.

\begin{array}{l}{\Rightarrow\left(x^{2}+2 x\right)-14=2 x+2} \\\\ {=>x^{2}+2 x-2 x-14-2=0} \\\\ {\Rightarrow x^{2}-16=0} \\\\ {\Rightarrow x^{2}-4^{2}=0} \\\\ {\Rightarrow x^{2}=4^{2}} \\\\ {\Rightarrow x=4}\end{array}

One even number = x=4

Other even number = x + 2 = 4 + 2 = 6

Hence required equation to determine two consecutive even number is x^2 -16 = 0 and required numbers are 4 and 6.
