Answer:
The solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Step-by-step explanation:
we can solve the system of equations to find the value of x and y and then verify if (1,3) is a solution or not.
The system of equation given is:

Solving:
Let:

Put value of y from equation 2 into equation 1

Now, put value of x in equation 2 to find value of y

So, the solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
The upper comment is correct
To make 8 inch tall column approximately 61 coins required.
Given,
Total one cent coins stacked on top of each other in a column = 50
Height of column = 378 inches
Approximate height of one coin = ( 50 / 378)
= 0.132 inches
To make an 8 inches tall stack No of coins required will be:
Number of coins required = ( total height / height of one coin )
= ( 8 / 0.132 )
= 60.60
≅ 61 coins
To make 8 inch tall column approximately 61 coins required.

Step-by-step explanation:
Given:
500 ml of ingredient to be mixed with 1000 ml of another ingredient.

Now we need to convert ml into Ounces.
Formula:


1. 3+2+1+2+3+1=12
2. 5+6+6+7+6+6=36
3. 2+4+3+3+2+4=18
Then add all those numbers up and divide them by 18.
12+36+18=66/18=3.6 you can round it up to c.4.
