<u>Given</u>:
The system of linear equations are
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute
in the equation 
Thus, we have;




Thus, the value of y is -17.
Substituting
in the equation
, we get;


Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
Answer:
The value of 0 is 0 - If you want to round its 37.1
Step-by-step explanation:
The value of 0=0
0
any other # besides zero
if you are wanting to round, you can round to the tenths place and say that 37.06 rounds up to 37.1
Start by finding 7% of the $23.20:

Now add this to $23.20:

Now, let's find 18% of this new total with tax to find the tip amount:

This is the tip amount. And finally, let's add this to the 24.824:

Not sure if you were given any instructions about rounding, but Ana's cost will be around $29.29.
Hope this helps.

Answer:
The answer is 4.
Step-by-step explanation:
Change 4 2/3 to 4 4/6 to match 11/6.
Add 4 4/6 and 11/6 and get 4 15/6.
Subtract 4 15/6 by 15/6 and get 4.
4 is the answer.
I hope this helps.
Have a nice day!
