Multiply to negative 60 add to negative 11
1.50c + 4.00a = 5,050
c + a = 2,200
-1.50 (c + a = 2,200)
1.50c + 4.00a = 5,050
-1.50c - 1.50a = -3,300
2.5a = 1750
a = 700
c + 700 = 2,200
c = 1500
700 adults and 1500 children attended the fair.
Answer:
(x - 6)² = 48
Step-by-step explanation:
We can solve it by completing square:
x² - 12x - 5 = 7
x² - 12x = 12
x² - 2*6x =12
We need to use formula
a² + 2ab + b² = (a + b)²
x² - 2*6x + 6² - 6² = 12
(x - 6)² = 12 + 36
(x - 6)² = 48
It’s B according to my calculations
Answer:
Step-by-step explanation:
We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.
Let us find probability of getting a club.
Now let us find probability of getting the ace of spades.
Now let us multiply these to find probability of getting a club and ace of spades.
Therefore, probability of getting a club and then the ace of spades .
