Answer:
x = 9
y = 6
Step-by-step explanation:
x / 12 = 6 / 8
x = 6/8 * 12 = 9
(y-4) / 4 = 3 / 6
y - 4 = 3/6 * 4 = 2
y = 6
We want to verify that x² + x - 12 = (x - 3)(x + 4)
We can prove this by factoring the left side and showing that it is equal to the Right side.
We should find factors of -12 that sum to +1.
-12 = 1 x -12 Sum = 1 - 12 = -11 No
-12 = 2 x -6 Sum = 2 - 6 = -4 No
-12 = 3 x -4 Sum = 3 - 4 = -1 No
-12 = 4 x -3 Sum = 4 - 3 = 1 Yes
Therefore
x² + x - 12 = (x - 3)(x + 4) which is equal to the Right side.
Latisha is correct because
4(-3) = -12, and
-3 + 4 = 1
Answer: Latisha
Answer:
x = y − 6 Is your answer
Step-by-step explanation:
y = x + 6
x = y -6
Answer:
20
Step-by-step explanation:
PEMDAS!!!
13 - 2(-14) ÷ 4
13 - [(-28) ÷ 4]
13 - (-7)
13 + 7 = 20
The experimental probability in this problem is given by the total amount of silver coins Clarisse pulled over the total amount of coins Clarisse pulled.
She pulled 48 silver coins out of the 60 she pulled in total. Set up a fraction:
This fraction can be simplified by dividing both the numerator and denominator by 12:
The experimental probability of pulling another silver token is
4/5.
