Solutions
1) <span>Lets use n as alex's number
</span>⇒ n x 1000
⇒ n ÷ 10
⇒ = 475
To solve the problem do the opposite steps
475 ÷ 1000 = n
n = <span>0.475
</span>
0.475 x 10 = n
n = 4.75
CHECK YOUR WORK
4.75 x 1000 = 4750
4750 ÷ 10 = 475
The answer is correct
⇒ The answer Alex is thinking of is 4.75

The easiest way is to break it down into smaller shapes. denied it into 3 rectangles and 2 squares fingers the areas of all of them and add them up.
First, you need to distribute.
5x-20= 3x+24
Then combine like terms
8x=4
then divide by 8
x=2
