Answer:
x = - 3 3/8
Its negative 3 3/8
Step-by-step explanation:
13x + 7 = 5x - 20
Subtract 5x from both sides
8x + 7 = -20
Subtract 7 from both sides
8x = -27
Divide both sides by 8
x = -27/8
x = - 3 3/8
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
----------> the value of A is 
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
therefore
the answer is
the value of A is
Answer:
40
Step-by-step explanation:
f(4) = 3(4²) - 2(4)
= 3(16) - 8
= 48 - 8
= 40
when x=4, f(x) = 40
Answer:
30
Step-by-step explanation:
To find the best prediction for the amount of numbered cards that will be drawn during the game, first find the probability of drawing a numbered card. There are 36 numbered cards and 48 total cards. So, the probability of drawing a numbered card is or .
Now, multiply the probability by the number of times a card will be drawn from the deck. Since there are 10 rounds and 4 players, a card will be drawn from the deck 10 × 4, or 40, times. So, multiply by 40.
Therefore, the best prediction for the amount of numbered cards that will be drawn during the game is 30.
