Answer:
$20.40
Step-by-step explanation:
First of all we find the value of 10%, so we do 24 ÷ 10 which equals to 2.4, then we find the halved value of 2.4, so we do 2.4 ÷ 2 which equals to 1.2. Then we add 2.4 and 1.2 together, which then gives us 3.6 as the number. We then subtract 3.6 from 24 which gives us 20.4, but we need in money terms so we change it to $20.40. Hope this helps.

Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1. 
 
        
             
        
        
        
Answer: 30
Step-by-step explanation: To solve this problem, we're going to have to use the Pythagorean theorem...
a² + b² = c²
24² + 18² = c²
576 + 324 = c²
c² = 900

30 
30 = c
