Answer:
or ![0.325\ liters](https://tex.z-dn.net/?f=0.325%5C%20liters)
Step-by-step explanation:
we know that
To find the total amount of juice Carlos mixed, sum the liters of orange juice plus the liters of pineapple juice
Let
x------> liters of orange juice
y-----> liters of pineapple juice
z----> total amount of juice mixed
so
![z=x+y](https://tex.z-dn.net/?f=z%3Dx%2By)
we have
![x=\frac{2}{10}\ liters](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B2%7D%7B10%7D%5C%20liters)
![y=\frac{1}{8}\ liters](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B8%7D%5C%20liters)
substitute
![z=\frac{2}{10}+\frac{1}{8}=\frac{4*2+5*1}{40}=\frac{13}{40}\ liters](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B2%7D%7B10%7D%2B%5Cfrac%7B1%7D%7B8%7D%3D%5Cfrac%7B4%2A2%2B5%2A1%7D%7B40%7D%3D%5Cfrac%7B13%7D%7B40%7D%5C%20liters)
Convert to decimal form
![\frac{13}{40}\ liters=0.325\ liters](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B40%7D%5C%20liters%3D0.325%5C%20liters)
Answer:
Infinitely many.
Step-by-step explanation:
y = 3x + 4
2y = 6x + 8
Basically you would fill in the variable for y into the second equation.
2 (3x + 4) = 6x + 8
Multiply 2 by the part in the parenthesis.
2 * 3x = 6x
2 * 4 = 8
Set up the equation and solve
6x + 8 = 6x + 8
Because the sides are the same, they cancel each other out. When two sides equal the same variable they have infinitely many solutions.
The value of the x and y are -1/4 and -1/2 if the system of equations are 2x + 3y = -2 and 2x + y = -1.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The two linear equations:
2x+3y+2=0
2x+y=-1
Solving by elimination method.
2x + 3y = -2
2x + y = -1
Subtract the equation first to second:
2y = -1
y = -1/2
Plug the above value in the equation second:
2x - 1/2 = -1
2x = -1 + 1/2
2x = -1/2
x = -1/4
Thus, the value of the x and y are -1/4 and -1/2 if the system of equations are 2x + 3y = -2 and 2x + y = -1.
