Answer:

13. 5 minutes

Step-by-step explanation:

This is a simple proportion problem. Make two fractions where one item is always on the top and the other on the bottom.

$\frac{3 min}{128 words} = \frac{x min}{ 576 words}$

Now, cross multiply (multiply the two numbers diagonal from each other and divide the diagonal with the x value)

576 x 3 = 1, 728

1, 728 / 128 = 13.5

How many solutions does the equation −2y + 2y + 3 = 3 have? One Zero Infinitely many Three

AnnZ [28]

Answer:

Infinitely many solutions.

Step-by-step explanation:

In the equation −2y + 2y + 3 = 3 we see only one variable, and that variable is of the first power. Ordinarily, we'd say that this equation will have 1 solution. However, if we combine like terms, we get 0 + 3 = 3, or 0 = 0, which is true for any and all y values. Infinitely many solutions.
