Answer:

x = 41 3/4

Step-by-step explanation:

(2 1/2)x -(3/4)(2x +5) = 38

(2 1/2)x -(1 1/2)x -15/4 = 38 . . . . use the distributive property

x = 38 +3 3/4 . . . . . . add 15/4

x = 41 3/4

_____

Another way to solve this is to "clear fractions" by multiplying the whole equation by 4:

10x -3(2x +5) = 152

4x -15 = 152 . . . . eliminate parentheses

4x = 167 . . . . . . . add 15

x = 41 3/4 . . . . . . divide by 4

Point T is located at (6, –2) and point S is located at (1, 13). What are the coordinates of the point that is 4/5 of the way fr

Darya [45]

Answer:

(2, 10)

Step-by-step explanation:

Making the points on a graph and creating a line between them, you can see the equation to connect the two points is -3x + 16. Then, because the points are 5 units apart horizontally, go to the point that is 4 units left of point T (1/4 of the way between T and S) and that is your point: (2, 10)

I apologize if this is incorrect :)
