a baseball glove was on sale for 5/6 of the original price. if the original price was \$90 what was the sale price

since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75

Couldn't you go 1/6 x \$90. 1/6 being the sale price because 5/6 + 1/6 = 6/6 which is the whole price. 1/6 = 0.166 as a decimal so you would multiply 90 x .16 = 14.40. then \$90.00 - 14.40 = 75.60 for the sale price.

What is the equation, in slope-intercept form, of the line that contains the points (3, -4) and (5 -6)

y = -x - 7

Step-by-step explanation:

As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2.  Thus, the slope of this line is m = rise / run = -2/2, or -1.

Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.

Subbing -4 for y and 3 for x, we get

-4 = -1(3) + b, which yields b = -1

Thus, the desired equation is

y = -x - 1

David says you can have an unlimited number of equivalent fractions to any given fraction. Is he right?

Yes, David is correct.
We can test our hypothesis by setting up an experiment.
1   2    4   6    7
2   4    8   16  14
AND SO ON!
yes, multiply the numerator and denominator by the same number again and again to keep getting different equivalent fractions.
