We have been given an equation w=\frac{3}{2}t-1 that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.

To solve our given problem, we will substitute w=7 in our given equation as:

7=\frac{3}{2}t-1

Let us solve for t.

7+1=\frac{3}{2}t-1+1

8=\frac{3}{2}t

8\cdot\frac{2}{3}=\frac{2}{3}\cdot\frac{3}{2}t

\frac{8\cdot2}{3}=t

\frac{16}{3}=t

Therefore, it will take \frac{16}{3} hours Joe to paint 7 walls.

Your friend rolls a number cube 500 times, how many times do you think an odd number will be rolled?
Mila [183]
250, and this is because of probability. Since half of the numbers are odd numbers, and half are even. It would be hard to determine, your probability would be 1/2. 1/2 of 500 is going to be 250.
