In the equation 0.75 - 5/8s = 44, how do you combine the like terms?

Leokris [45]

s = 71.6

____________

0.75 - 5/8s = 44

3/4 - 5/8s = 44

3/4 - 3/4 + 5/8s = 44 + 3/4

5/8s = 44 3/4

5/8s / 5/8 = 44 3/4 / 5/8

s= (179/4 / 5/8)

s= (179/4 * 8/5)

s= (179/1 * 2/5)

s= (358/5)

s= (350/5 + 8/5)

s= (70 + 8/5)

s= (70 + 1 + 3/5)

s= 71 3/5

s= 71.6

I checked this and its correct :P Sorry about the late answer, hope this helps!

What is the slope of the line that goes through the points (7,10) and (3,-3)

PilotLPTM [1.2K]

Ypu would subtract Y from the other points Y
$- 3 - 10 = - 13$
Then you would subtract X from the ither points X.
$3 - 7 = - 4$
Then you would put the Y value over the X
$\frac{ - 13}{ - 4}$
Then simiplify
$\frac{13}{4}$
