5.55/0.15 = 37 is an equation hope this helps
Answer:
-5/13
Step-by-step explanation:
I don' treally sure if it correct
Answer:
Part a) The speed is 
Part b) After 4 seconds the trains is 24 ft along the track
Part c) 
Step-by-step explanation:
we have

This is the equation of a line in slope intercept form
where
s(t) is the position of a model train in feet
t is the time in seconds
Part a) How fast is the train moving?
The speed of the train is equal to the slope of the linear equation so
The slope m is equal to

therefore
The speed is 
Part b) Where is the train after 4 seconds?
For t=4 sec
substitute the value of t in the equation and solve for s

therefore
After 4 seconds the trains is 24 ft along the track
Part c) When will the train be 29 feet along the track?
For s(t)=29 ft
Substitute the value of s(t) in the equation and solve for t

subtract 14 both sides


Divide by 2.5 both sides

rewrite

7 times 7 is 49
7 times 6 is 42
and 7 times 2 is 14
so 49t+6r+2 would be your answer
Step 1: Cross-multiply.
(x+3)^1/2=(3x+7)^1/4
Step 2: Subtract 6x from both sides.
4x+12−6x=6x+14−6x
−2x+12=14
Step 3: Subtract 12 from both sides.
−2x+12−12=14−12
−2x=2
Step 4: Divide both sides by -2.
−2x/−2=2/−2
Answer:
x=−1
