Answer:
The cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
Step-by-step explanation:
Let each pound of trail mix cost 
dollars and each pound of jelly beans cost 
dollars.
Given:
7 pounds of trail mix and 9 pounds of jelly beans cost $ 37.
So, 
--------------- 1
Also, 5 pounds of trail mix and 3 pounds of jelly beans cost $ 17.
So, 
--------------- 2
Multiplying equation 2 by -3, we get
Now, adding equations 1 and 3, we get
Now, plug in 
in equation 1 and solve for .
Therefore, the cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
Evaluate : 8 - 9 + (-2)
8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)
-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)
Finally, your answer to this question is -3.
Hey! I'll provide the steps required.
First, solved the proportion by cross multiplication.
Then use the commutative property to reorder the terms as well as multiply the numbers.
90x = 9720
Finally, divide it by 90.
x = 108
3x + 7y = 14
Subtract 3x from both sides
7y = -3x + 14
Slope is equal to -3.
<em>Answer : </em><em>15 days</em>

<em>Explanation?</em>
<em>Well considering it takes them 3 days to make 8, we would divide 40 by 8 which is 5 and multiply 3 and 5 to get 15 days in total.</em>
