Julia bought stock at $281/8 per share. The value of each share increased by $65/8. How much is each share of stock now worth?​
const2013 [10]

The worth of the share of stock is $34\frac{3}{4}.

<h3>What is the worth of the stock now?</h3>

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A mixed fraction is a fraction that is made up of a whole number and a proper fraction.  A proper fraction is a number where the numerator is less than the denominator.

The worth of the stock now = purchase price + increase in the share price

28 1/8 + 6 5/8

34 \frac{1 + 5}{8}

34\frac{6}{8} = 34\frac{3}{4}

Find k given that these three points are collinear.<br> A(0, -2), B(2, 0), and C(5, k)
goldfiish [28.3K]

Answer:

k = 3.

Step-by-step explanation:

If they are collinear the slope of AB = the slope of BC, so :-

(0- (-2)) / (2 - 0) = (k - 0) / (5 - 2)

2/2 = k/3

1 = k/3

k = 3.
