It decrease and it percentage is 53
Answer:
Step-by-step explanation:
it no solution
No solution is parallel to each other.
solution crosses each other.
infinite is only one line.
AREA OF A RECTANGLE IS 42 UNITS
Rectangle: Triangle:
A = L * W A = hb / 2
A = (x-8) * 6 A = (7(x-3)) / 2
A = 6x - 48 A = (7x - 21) / 2
Since the problem states that both rectangle and triangle have the same area.Then:
6x - 48 = (7x - 21) / 2
1) Eliminate the denominator 2 by multiplying both sides by 2.
2 * (6x - 48) = 2 * ((7x - 21) / 2)
12 x - 96 = 7x - 21
Find x. Transfer like numbers and change their signs.
12x - 7x = 96 - 21
5x = 75
5x / 5 = 75 / 5
x = 15
Substitute x by its value:
Rectangle: Triangle
A = (x-8) * 6 - A = (7(x-3)) / 2 Areas of both Rectangle
A = (15 -8 ) * 6 A = (7(15-3)) / 2 and Triangle is the same.
A = 7 * 6 A = (7 * 12) / 2
A = 42 units A = 84 / 2
A = 42 units
Answer:
B. 23 games.
Step-by-step explanation:
Current balance: $469
Goal balance: $825.50
Profit per game: $15.50
- 825.50 - 469 = 356.50
They only need $365.50 in order to reach the goal.
- 356.50 ÷ 15.50 = 23
They need to sell 23 games, each selling for $15.50, in order to reach their goal balance, of $825.50.
- Therefore, the answer is B.
