morpeh [17]

Answer:

W = (1/7) t

Step-by-step explanation:

At t = 0, W  =  0

At t = 56 minutes , W = 8 inches

W = k*t    The y intercept = 0 because t = 0 W = 0

8 inches = k * 56 minutes

k = 8 / 56

I don’t understand this I would like some help plz!!!
Andrew [12]

So basically, these questions want you to find the variable<em> x</em>, which you can do by isolating the variable.


3) x * 1/2 = 1/3 <-- To isolate the x in this case, you want to divide both sides by 1/2, aka multiply by 2.

x = 2/3


4) x * 3 = 2 <-- To isolate x, you want to divide both sides by 3

x = 2/3


5) 1/4 * x = 1/6 <-- To isolate x, you want to divide both sides by 1/4, aka multiply by 4.

x = 4/6 = 2/3


6) 4 1/2 * x = 1 1/2 <-- First, let's make these into improper fractions

9/2 * x = 3/2 <-- To isolate x, you want to divide both sides by 9/2, or multiply both sides by 2/9

x = 6/18 = 2/3
