Answer:
5.60 pounds each
Step-by-step explanation:
This is the dry mixture problem.
Let x = the number of pounds of the first type of candy
Therefore, number of pounds of second type of candy = 10-x
Value of first candy + value of second candy = value of mixture
Value of any candy = cost per pound of candy * weight of candy
Thus:
4x + 6(10 - x) = 5.60(10)
4x + 60 - 6x = 56
-2x + 60 = 56
-2x = -4
x = -4/-2
x = 2
Therefore, the number of pounds of first type of candy = 2 pounds
The number of pounds of second type of candy = 10 - 2 = 8 pounds
Check
$4(2) + $6(8) =
8 + 48 = $5.60(10)
$56 = $56
Answer: 8a^2 + 2c^2 - 2c
Step-by-step explanation: It is a simple addition between 6a^2+2a^2. The other terms remain the same.
The pair is any numbers, 1 positive and one negative, that add up to -3.
Here is a sample;

Answer:
10 were eaten
Step-by-step explanation:
If we have 15 cupcakes and 2/3 of them were eaten, we multiply 15 times 2/3
15*2/3
12*2 = 30
30/3 = 10
10 of the cupcakes were eaten
