There are two ways to solve this.
The first way is logically.
Mary can
-wear a pink dress with black shoes -wear a pink dress with white shoes
-wear a blue dress with black shoes -wear a blue dress with white shoes
-wear a yellow dress with black shoes - wear a yellow dress with white shoes
Count them up, and you'll get six combinations!
Another way is simply mathematically, which is easier in my opinion.
3 (different colored dresses) × 2 (different colored shoes) = 6 (combos)
Apples : 5 3/4 * 2 1/2 = 23/4 * 5/2 = 115/8 = 14 3/8 lbs
flour : 6 3/4 * 2 1/2 = 27/4 * 5/2 = 135/8 = 16 7/8 cups
margarine : 1/8 * 2 1/2 = 1/8 * 5/2 = 5/16 cups
sugar : 3 5/8 * 2 1/2 = 29/8 * 5/2 = 145/16 = 9 1/16 cups
cinnamon : 2 * 2 1/2 = 2/1 * 5/2 = 10/2 = 5 teaspoons
Multiply the number of atoms in 1 mole by .44 so...2.7x10^23 atoms
Answer:
correct answer is B, y= (-2/3)X+12
Step-by-step explanation:
use the two point system to find equation of line segment, or you can just put one of the point from on equn of the lines (in options) to check whether it's satisfying the equation or not!
