Answer:
<h3>A. y=-2x+3z+25</h3>
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<u>To solve:</u>
<h3>2x+y-3z=25</h3>
<u>First, you have to subtract by 2x-3z from both sides.</u>
<u>Solve.</u>
- <u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>
I hope this helps, let me know if you have any questions.
Answer:50.000+2000+400+80+9
Step-by-step explanation:
So, we are dealing with function notation.
F(x) can be thought of as Y= if it's easier.
So f(4) is what is the output value if X = 4. So we just plug 4 into the function wherever we see x.
Answer:
Answer:
The required model is
60 pounds of concrete each bag make.
Step-by-step explanation:Consider the provided information.
Let the number of concrete bags are used is represented by y.
Part (A)
3.5 bags of concrete mix for a new set of stairs and 2.25 bags of concrete mix for a garden wall.
This can be written as:
Timothy mixed 345 pounds of concrete in all.
Therefore,
Hence, the required model is
Part (B) Solve for y. How many pounds of concrete does each bag make?
Consider the above equation.
Solve the equation for y as shown.
Add the like terms.
Divide both the sides by 5.75
Hence, 60 pounds of concrete each bag make.
