Answer: 28
Solution:
(Based on the given conditions formulated:)
40 x (1 - 30%)
40 x (1 - 0.3)
Calculate the sum or difference
40 x 0.7
Calculate the product or quotient
= 28
What number you have to multiply 2 to get 5.
Or 2*x=5 solve for x
We have the following number:
23.5
This number can be written as:
23 + 0.5
Or:
23 + 1/2
So, the new expression gives us two new numbers. In this way, we can say that:
23 = Twenty three
1/2 = a half
In conclusion, the number 23.5 can be written as follows:
<em>23.5 = Twenty three and a half</em>
8x+16=8x-16 is no solution because it is 32=0
-3x-17=-(17+3x) is infinitely many solutions because it is 0=0
9x+27=27 is one solution because it is x=0
2x-6=6+2x is no solution -12=0
