3. The equation s = w -10e / t models the speed in words per minute, s, at which someone types. The speed, s, is related to the number of words typed, w, the number of errors, e, and the time spent typing in minutes t. a) Rearrange the formula to isolate w.

b) How many words can Jack type if his typing speed is 50 words per minute, he types for 5 minutes, and he makes 2 errors?

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
