Answer:
40 pounds
Step-by-step explanation:
Given: Cost of a candy
=
per pound
Cost of candy 
Total amount of mixture of be produced = 
Selling price of mixture = 
Let´s x be the amount of
to be mixed in the mixture.
∴ Cost of
in the mixture = 12x
Next, Cost of
in the mixture = 
And we know the cost of final mixture = 
Now, putting all the value in the equation
⇒ 
⇒ 
⇒ 
∴ 
∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.
Answer:
Quadratic Property 2x^2-18=0
Square Root Property x=√9 or x=+3 or x=-3
Step-by-step explanation:
Quadratic Property or a quadratic Function is of the form ax^2+bx+c=0. So our task is to equate the given expression to zero. We can equate the expression to zero by subtracting 11 on both the sides. In doing so, we get 2x^2-18=0. This is the quadratic Property of the given Expression.
Square property is finding the value for x. we have make x equal to some value. Since we already have the quadratic Property as 2x^2-18=0, we can use this to find the value of x.
so, 2x^2=18
or x^2=18/2=9
or x=√9= +3 or -3.
Answer:
21
Step-by-step explanation:
average 9 pounds per three weeks
divide 9 in 3 three weeks
3 pounds per week
7 times 3 is 21
If you’re trying to find the value of x it is -5
