Jasmine wants to have an equal quantity of forks and spoons, what is the least number of packages of forks jasmine should buy to
vlada-n [284]

Answer:

6 packages of forks

Step-by-step explanation:

If Jasmine wants to have an equal quantity of forks and spoons, we need to list the multiples of each quantity and determine the least common multiple (LCM).

Forks: 10, 20, 30, 40, 50, 60, 70, 80, 90

Spoons: 12, 24, 36, 48, 60, 72, 84, 96

The LCM in this example is 60. In order to have exactly 60 forks and 60 spoons, Jasmine will need to buy 6 packages of forks [60 ÷ 10 = 6] and 5 packages of spoons [60 ÷ 12 = 5].

Find the slope of the line passing through each of the following pairs of points.
boyakko [2]

If you start at (-3,1) and end up at (0,3), you will have increased x by 3 and y by 2.  Thus, the slope of this line is  m = rise / run = 3 / 2.

Using the point-slope form of the equation of a straight line, we get:

y - 1 = (3/2)(x+3).

This could be rewritten in other forms:

y = 1 + (3/2)x + 9/2, or y = 2/2 + (3/2)x + 9/2, or y = (3/2)x + 11/2.
