Answer:
10 quarters
40 dimes
Step-by-step explanation:
q + d = 40
25q + 10d = 625
25 > 10
q < d
25(10) = 250
10(40) = 400
$2.50 + $4.00 = $6.00
Here is the graphed equation :)
Answer:
38
Step-by-step explanation:
(11+13)+14
11+13=24
24+14=38
Answer:
7000
Step-by-step explanation:
This is because when you round to the significant figure, you basically look at any digits at the start of the number, which isn't zero. In this case, it would be in the thousands place 7284. So you round 7284 to the nearest thousands, which, would be 7000
Answer: The answer is NO.
Step-by-step explanation: The given statement is -
If the graph of two equations are coincident lines, then that system of equations will have no solution.
We are to check whether the above statement is correct or not.
Any two equations having graphs as coincident lines are of the form -

If we take d = 1, then both the equations will be same.
Now, subtracting the second equation from first, we have

Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.
For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.

Thus, the given statement is not correct.
