Answer:
x -2y = -9
Step-by-step explanation:
We can start by swapping the coefficients of x and y, then negating one of them. We can finish by evaluating the expression at the given point to find the constant.
2x -4y = constant
2(1) -4(5) = -18 = constant
So, an equation could be ...
2x -4y = -18
We notice that all of the coefficients of this equation are divisible by 2, so we can remove a factor of 2 from the equation:
x -2y = -9

Step-by-step explanation:
The number of protons in an element is what determines the atomic number. Take Aluminum for instance. There's thirteen protons in the element of aluminum and the atomic number for that element is thirteen.
Hope this helps! :)
Since Molly can make 4 pancakes in 6 minutes if you divide 60 by 6 you get 10 so Molly can make 10 pancakes every hour
