How to solve the problem that three out of five equals nine out of ten
5x = 9 / 10 × 3 / 5
5x = 27 / 50
X = 27 / 50 △ 5
X = 27 / 250
X minus 5 / 3 x equals 5 / 3
X=-2/5
Find the solution of 7.5x-9.25 equal to 3.3.5
Urgent, correct answer, I will give you more reward
Wrong. 7.5x-9.25 is 33.5
Your problem. The most powerful problem about solving X
7.5x-9.25=33.5
7.5x =33.5+9.25
=42.75
X = 42.75 / 7.5 (/ = divided by)
=5.7
We get x = 5.7
x＋1-1/2=3/5x
2/5x+1/2=0
X=-5/4
What is limx → 1 x ^ 2-5x + 4 / x ^ 3-1
The answer is - 1
X + 3 = 5x, what is x equal to?
x+3=5x
5x-x=3
4x=3
x=3÷4
x=0.75
17 / 25 of a book is 51. How many pages does this book have?
Seventeen out of twenty-five of a book is 51, and this book has 51 / 17 / 25 = 75 pages
How many pages does this book have?
That's 85 pages
8.25 - (4 / 17 + 1 / 4)=
8.25 - (4 / 17 + 1 / 4)
=8.25-0.25-4/17
=8-4/17
=7 and 13 / 17

Add 1 from - 55 to get a series of integers, - 54, - 53, - 52 Excuse me: (1) what is the 100th integer? (2) What is the sum of these 100 integers?
(1) The 100th integer is - 55 + 100 = 45; (2) the sum of these 100 integers is (- 54) + (- 53) + (- 52) + (- 1) + 0 + 1 + +（45）=-（1+2+… +54）+（1+2+… +45）=-（46+47+48+49+50+51+52+53+54）=-450．
