Answer:
4 degrees
Step-by-step explanation:
24 degrees :6 hours
divide by 6 for the unit rate.
4 degrees : 1 hour
Step-by-step explanation:
given :
2x - 3y = 11
-6x + 8y = 34
find : the solutions of the system by using Cramers Rule.
solutions:
in the matrix 2x2 form =>
[ 2 -3] [x] [11]
=
[-6 8] [ y] [34]
D =
| 2 -3 |
|-6 8 |
= 8×2 - (-3) (-6)
= 16-18 = -2
Dx = | 11 -3 |
| 34 8 |
= 11×8 - (-3) (34)
= 88 + 102
= 190
Dy = | 2 11 |
|-6 34 |
= 2×34 - (-6) (11)
= 68 + 66
= 134
x = Dx/D = 190/-2 = -95
y = Dy/D = 134/-2 = -67
the solutions = {-95, -67}

Answer:
I believe it would be 86 cups left of milk.
Step-by-step explanation:
8 gallons= 128 cups of milk
3 quarts= 12 cups
Plus the 1 cup of milk he had equals 141 of milk in total
Now the customer wants 2 gallons (32 cups of milk), 5 quarts ( 20 cups), and 3 cups which is 55 cups of milk.
Now we minus what the customer bought from what the shop keeper had so:
55-141=86
