Answer:
50,803,200 ways
Step-by-step explanation:
In this situation, since you should alternate girl-boy or boy-girl, the line-up can either start with a boy or a girl kicking which would yield one of the two following patterns:
BGBGBGBGBGBGBG or GBGBGBGBGBGBGB.
For each of those patterns, there are 7! ways to arrange all boys and 7! ways to arrange all girls. The number of ways that a line-up can be made for one round of kicking is:
There are 50,803,200 ways to set the line-up.
In this problem you would set these two equations equal to each other.
$8+ $1.50x = $10+ $1x
After this you would simplify the equation to isolate x (being the number of toppings you put on the pizzas)
$8+ 1.50x =$10+ 1x
-8 -8
----------------------------
$1.50x = $2 + $1x
-1x -1x
---------------------------
$.50x/.50 = $2/.50
_______________
x= 4 toppings and the pizzas would equal $14 total
Answer:
(2.5, 2.5)
Step-by-step explanation:
Coordinates of midpoint
Answer:
D
Step-by-step explanation:
Given
- 12 ≤ 2x - 4 < 10 ( add 4 to all 3 intervals )
- 8 ≤ 2x < 14 ( divide all 3 intervals by 2 )
- 4 ≤ x < 7
