First you need to find your total amount of marbles and this number will be your denominator (on the bottom).
8 + 14 + 12 = 34
Then you see how many black marbles are in the bag and this number will be your numerator (on the top).
The probability Jose will pick a black marble is 8/34 but you always reduce your fractions so the correct answer is 4/17.
Answer:
y=2x-3
Step-by-step explanation:
the negative 3 represents the y intercept and the 2 represents the slope.
Answer:
supplementary angle = 60 , complementary angle : none
Answer:
x - y = 3
2x - y = 2
Step-by-step explanation:
x = 3 + y
2(3 + y) - y = 2
6 + 2y - y = 2
y = 2 - 6
y = -4
x = 3 + (-4)
x = 3 - 4
x = -1

Hello!
Oscar is correct, because all the steps he has taken to calculate the final price of the book are right and he has found the final price of the book.
Kim is incorrect because the steps she has taken to calculate the final price are not right, and she will not find the right final price.
YES, they have enough money to buy the book. Simply take all the steps Oscar took and calculate the final price.
28.50 × 30% = 8.55
28.50 - 8.55 = 19.95
19.95 × 10% = 1.995
19.95 + 1.995 = 21.945
This can be rounded to 21.95.
Since $21.95 is LESS than $22.00, they have enough money for the book.
