I'm assuming you want us to solve for the unknown variable z

10(z-2)=1+4

Combine like terms on the right side

10(z-2)=5

Use the distributive property on the left side

10z-20=5

Add both sides by 20 to cancel out the "-20" on the left side

10z=25

Divide both sides by 10

z=2.5

That is the value of the known variable, z, in this equation. Let me know if you need any clarifications, thanks!

x-2=1/2

z=1/2+2

z=5/2

5 throws and Mean Score is 32 are the clues

3. Guess and check

The method to this thingy is called guess and check. There is another method which is slightly harder and i just don't want to do it.

Let's just say his scores were... 5, 6, 4, 5,10Add them up and you get 30Then 30/5

Let's try bigger numbers

20+25+20+20

If you like this method, you may try it another method is called work Backwards

5x32=160

Then divide 160 by 5 to double check and you get 32!!

========================================

Therefore, the answer s 160 as his total score

hope this gives you a clue to what we are doing and when you have a question like this, I really hope you understand the concept
