Answer:
If an equal number of each brand was ordered, how many dozens of each brand were ordered?
Step-by-step explanation:
in order to determine the number of balls purchased, we must first determine the difference in price between them = $2 - $0.90 = $1.10
since the total difference in price was $660 and an equal number of balls were purchased, then the number of balls purchased = $660 / $1.10 = 600 balls
to determine the number of dozens purchased of each brand we just divide 600 by 12 = 50 dozens
Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3
Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1
The solution (-1,3)
Answer: 
Step-by-step explanation:
Let n= Number of packs John needs.
Tiles in 1 pack = 6
Tiles in <em>n</em> pack = <em>6n</em>
If he needs at least 100 tiles.
then
6n ≥ 100
The required inequality:
Answer:
A, C, and E are correct.
Step-by-step explanation:
B is incorrect because a line that passes through point F would be the bisect, not line segment AB
D is incorrect because it just is.
So each track practice =3 miles
6miles/3miles= 2
