Answer:

s = 9t + 18

Explanation:

Set up your equation

s - 15 = 9t + 3

Now get s by itself by adding 15 to both sides

s + 0 = 9t + 3 + 15

s = 9t + 18

If you know the value of t, plug that into the equation to solve further.

How many times does 12 go into 60?

5 times.

Y + 2 =3 (x-6) <br>find the slope and a point on the line​
Alex777 [14]

Answer:

slope = 3, point = (6, -2)

Step-by-step explanation:

This is in point-slope form which looks like this : y-y1 = m(x-x1).

m is the slope, an x1 and y1 are the x and y coordinates of the point. Remember to flip the sign of the numbers for the points i.e. the y+2 in the equation becomes -2 for the point.
