12...? I think?
Since she has 9 left and it only says that she gave 3 away..
Answer: X = 2
Step-by-step explanation: To find the value of "X" in this equation, we first need to subtract 3 from both sides.
Image provided.
Divide the second amount by five to find out how much it costs at the second farmers market to get 1 pound of bananas.
5/5=1
4.50/5=.9
.9>.8 so the first farmers market had a better deal.
Answer:
(3)
Replcaing equation (3) into equation (2) we got:

And solving for Y we got:



And solving for X from equation (3) we got:

So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
Step-by-step explanation:
For this problem we can work with the concentration of water and orange juice.
Let X the amount for the orange juice with 25% content and Y the amount for the orange juice with 5% of content
Using the concentration of orange juice we have:
(1)
And for the water we have:
(2)
If we solve for X from equation (1) we got:
(3)
Replcaing equation (3) into equation (2) we got:

And solving for Y we got:



And solving for X from equation (3) we got:

So we need 3L of orange juice with 25% of concentration and 17 L of orange juice with 5% of concentration
