Answer:
x=19
Step-by-step explanation:
In order to solve for x, we want to add the equations to equal 180.
6x+12+3x-3=180
9x+9=180
9x=171
x=19
We have a
number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that
begins in -3 and closes in 8, that is,
<em>takes values from -3 to 8</em>. In a mathematical language this is given by
the following statement:

Answer:
There is no picture or graph to go with the question so I am afraid I will not be able to give you a specific answer.
To find out if a point (x, y) is on the graph of a line, we plug in the values into that equation and see if we get a true statement, such as 10 = 10. If we get something different, like 6 = 4, we know that the point is not on the line because it does not satisfy the equation. Plug in (-301, 601) into the equation of the line to see whether that point lies on it or not.
Step-by-step explanation:
Suppose the equation of the straight line that passes through E and F is this:
y = 7x + 2
We are to figure out whether or not the point (1, 10) lies on that line. In order to do this we would plug in (1, 10) into the equation, with 1 being x and 10 being y.
10 = 7(1) + 2 = 7 + 2 = 9
10 = 9 is a false statement. Therefore, the point (1, 10) does NOT lie on the line y = 7x + 2.
If you were to provide an image or graph that shows the equation of line AB then perhaps I would be able to answer your question with a specific answer.
Answer:
56 dollars are earned for recycling 28 pounds of copper.
Step-by-step explanation:
Quantity of copper recycled = 
pounds
Amount earned in dollars for recycling pounds of copper = 
Also,
Quantity of copper recycled = 
pounds
Therefore,
Amount earned in dollars for recycling pounds of copper = 
dollars
So,
56 dollars are earned for recycling 28 pounds of copper.
Answer:
m = 16
Step-by-step explanation:
Given expression 2m−13 and m+3.
We have to find value of m for which both the expression are equal.
To find that value we will equate both the expression and solve as given below
2m−13 = m+3
adding 13 on both LHS and RHS
2m−13 + 13 = m+3 + 13
=> 2m = m +16
subtracting m from LHS and RHS
2m - m = m +16 - m
=> m = 16
Thus, value of m will be 16.
to validate this lets put value of m as 16 in both the equation
2m - 13 = 2*16 - 13 = 32-13 = 19
m+3 = 16+3 = 19.
Thus, we see for m = 16 , both expression has equal value which is equal to 19.
