ANSWER
Alex needs to mix one pound of dried fruit with

pounds of walnuts.
EXPLANATION
It was given that, Alex mixes

pounds of walnuts with

pounds of dried fruit.
We can write the ratio,

Let

represent how many pounds of walnuts Alex needs to mix with one pound of dried fruit.
Then we can again write the ratio,

We can therefore write the proportion,

This can be rewritten as,

We solve for x to obtain,

This implies that,


Hence Alex needs to mix

pounds of walnuts with one pound of dried fruit.
In triangle ABC angle c = 180-78-40 = 62 degrees
For the triangles to be congruent angle z must equal angle C
Solve for x:
2x + 8 = 62
Subtract 8 from both sides:
2x = 54
Divide both sides by 2:
X = 27
Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.
A. False
B. True
C. True
This is the associative property of addition
