Answer:
$11
Step-by-step explanation:
Set up the system of equations
18x + 9y = 45
20x + 12y = 52
Let's try to get y on one side for the first equation.
9y=45-18x
y=5-2x
Now substitute it into the second equation.
20x + 12(5-2x) = 52
20x + 60 - 24x = 52
-4x = -8
x = 2
Now solve for y using the first equation.
18(2) + 9y = 45
36 + 9y = 45
9y = 9
y = 1
Now that we know x and y we can solve for the price of 4 hot dogs and 3 drinks.
4(2) + 3(1) = z
8 + 3 = z
11 = z
That means that the price is 11 dollars.
Answer: 13/22
Step-by-step explanation:
Number of red crayons = 9
Number of blue crayons = 5
Number of yellow crayons = 8
Total number of crayons = 9+5+8 = 22
The probability of selecting either ia blue or a yellow crayon will be:
= 5/22 + 8/22
= 13/22
