Answer:
x = 2
Step-by-step explanation:
Set the equations equal to each other
x + 2 = -3x + 10
+ 3x + 3x Add 3x to both sides
4x + 2 = 10
- 2 - 2 Subtract 2 from both sides
4x = 8 Divide both sides by 4
x = 2

To solve for a variable, you need to get it (x) by itself.
x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x =

Check your work by plugging in

for x and then

.

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63

² - 14 + 31 = 63 Square

46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
So,
x is

In this question a vital information has been provided. This information can be used for determining the answer to the question that is asked. It is given that 120% of a certain number is 360 pound. The 100% value of the number needs to be determined.
Let us assume the number to be = x
Then
120x/100 = 360
12x/10 = 360
12x = 360 * 10
12x = 3600
x = 3600/12
= 300
Now we can say that the 100% of the number or the actual number is 300 pounds. I hope the problem is clear to you and you can understand the trick involved in the question.
Answer:
£72.00
Step-by-step explanation:
60*20% (0.20) = 12
60 (original price) + 12 = 72
therefore, the original price of the bag was £72.00
1/8 is the mode. It appears most often
