Answer:
1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3
2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3
3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12
4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5
5. To put x by itself, you subtract 1 by 4, giving you x<-3
1/620 is the simplest form of 2/1240
all you had to do was simplify
2 divided by 2=1
1240 divided by 2=620 <span />
Answer:
T must be 3/(3+1) or 3/4ths of the way between point d and f.
Take (dx, dy) and add 3/4 (fx-dx, fy-dy) by components and that will be point T (Tx, Ty)
You find the distances between d and f in x and y and then move 3/4 of that distance from d.

Im not too sure, I got the answer from my last test. It might be wrong
(3+6X(5+4)÷3-7) the answer is 14
6(n+5)=16
