To calculate the percentage increase:
First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number
Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.
So in the problem:
First step:Increase = 1000 – 100
Increase = 900
Second:
% increase = 900 / 100 x 100%
increase = 900% increase
Answer:
The selling price of the tea set should be: The selling price of the tea set is $2170
$1400 x . 55 = $770.
To solve this problem you must apply the proccedure shown below:
1. You have that the following information given in the problem above: The<span> photograph is reduced by a scale factor of 3/8 and the original had a length of 20 inches,
2- Therefore you have:
length=20 inches-</span>(20 inches x 3/8)<span>
length=20 inches-7.5 inches
length=12.5 inches
3- Then, as you can see, the answer is: 12.5 inches.</span>
Answer: 3x
Step-by-step explanation:
*Remember BIDMAS*
b- brackets i- Indices (exponents) d- division m- multiplication a- addition s- subtraction
(*Reminder* exponents can be written on a keyboard like 2 squared is 2^2)
you need to follow these steps to be able to solve any equation
if there is no brackets like yours then add to make it easier
3x^2 - 4x - 2 = (3x^2) - 4x - 2
From the steps I showed you indices is first so 3x multiplied by 3x is 9x
now there is nothing left except for subtraction so solve from left to right always so 9x - 4x - 2 is 5x then 5x - 2 is 3x, x doesn’t change or gets subtracted.
i hope it helped :)
