To find one tenth of 119.9 just divide 119.9 by 10
They didn’t use a ruler I think they made their own materials from what they had. Also thank you.
So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!
Answer:
Im sorry im not sure how to do this either lol :/
Step-by-step explanation:
3/(5x) + x = 3/(5x) + x/1 * (5x)/(5x)
= 3/(5x) + 5x²/5x
= (3+5x²) / 5x
