Answer:
C
Step-by-step explanation:
You take the fractions and turn them into mixed numbers. You do that by multiplying the whole number with the denominator and adding the numerator for the new numerator and the denominator stays the same. Now, you'd get -45/8 + 7/2. Change the denominator of the second one to 8 so you can add them, do this by multiplying the numerator and denominator by 4. Now you get -45/8 + 28/8. -45 +28 is -17 so your answer is -17/8. If you need it In mixed form, 8 goes into -17 2 times so you get -2 and the remainder 1/8 so -2 1/8.
Answer:
B

Answer:
32 cups
Step-by-step explanation:
To find the total number of cups, we have to convert the measures that are not in cups to cups and add
1 quart = 4 cups
4 quarts = 4 x4 = 16 cups
1 pint = 2 cups
6 pints = 2 x 6 = 12 pints
total number of cups = 16 + 12 + 4 = 32 cups
Problem 1
Solving the system:
6A + 10B = 108
4A + 12B = 104 where A = cost of tickets in section A and B = cost of tickets in section B
A = 8
Problem 2
(10, -6)
Just subtract x + 3y = -8 from x + y = -14
