You need 20 teaspoons of red paint
15/x. The quotient means to divide, and you divide the first number by the second
Answer:
Marcy paid $4.15
Step-by-step explanation:
Given
Represent hotdogs with x and chips with y.
So, we have:
<u>Jamal</u>
![3x + 2y = 4.85](https://tex.z-dn.net/?f=3x%20%2B%202y%20%3D%204.85)
<u>Kenny</u>
![5x + 6y = 9.55](https://tex.z-dn.net/?f=5x%20%2B%206y%20%3D%209.55)
<em>See attachment for complete question</em>
Required
Determine the amount for 2x and 3y
From Jamal's and Kenny's orders we have:
--- (1)
--- (2)
Multiply (1) by 3
![3 * [3x + 2y = 4.85]](https://tex.z-dn.net/?f=3%20%2A%20%5B3x%20%2B%202y%20%3D%204.85%5D)
--- (3)
Subtract (2) and (3)
![9x - 5x + 6y - 6y = 14.55 - 9.55](https://tex.z-dn.net/?f=9x%20-%205x%20%2B%206y%20-%206y%20%3D%2014.55%20-%209.55)
![9x - 5x = 5](https://tex.z-dn.net/?f=9x%20-%205x%20%3D%205)
![4x = 5](https://tex.z-dn.net/?f=4x%20%3D%205)
Solve for x
![x = \frac{5}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5%7D%7B4%7D)
![x = 1.25](https://tex.z-dn.net/?f=x%20%3D%201.25)
Substitute
in ![3x + 2y = 4.85](https://tex.z-dn.net/?f=3x%20%2B%202y%20%3D%204.85)
![3 * 1.25 + 2y = 4.85](https://tex.z-dn.net/?f=3%20%2A%201.25%20%2B%202y%20%3D%204.85)
![3.75 + 2y = 4.85](https://tex.z-dn.net/?f=3.75%20%2B%202y%20%3D%204.85)
Solve for y
![y = \frac{4.85 - 3.75}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B4.85%20-%203.75%7D%7B2%7D)
![y = \frac{1.10}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1.10%7D%7B2%7D)
![y = 0.55](https://tex.z-dn.net/?f=y%20%3D%200.55)
So, the cost of 2x and 3y is:
![Cost = 2x + 3y](https://tex.z-dn.net/?f=Cost%20%3D%202x%20%2B%203y)
![Cost = 2*1.25 + 3*0.55](https://tex.z-dn.net/?f=Cost%20%3D%202%2A1.25%20%2B%203%2A0.55)
![Cost = \$4.15](https://tex.z-dn.net/?f=Cost%20%3D%20%5C%244.15)
Answer:
You have left a tricky Algebra question, So there are two different ways you can go about solving this.
1. If you are solving for the variable x then your answer is x=
.
2. If you are trying to solve for y then your answer is y= ![\frac{6}{5x}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B5x%7D)
Step-by-step explanation:
I have used an online algebra calculator to test my answers against and they are 100% correct. (as seen in the picture).
