so we have 16=4(9-x) we calculate this equation
16=(4*9)_x*4
so 16=36-4x
wich means these 2 equations are equivalent
Answer:
C. Reflection over x- axis, down 6 right 3
Step-by-step explanation:
Let's first come up with an equation that we can use to solve this problem.
Total Cupcakes= Cupcakes in each tin • the number of tins.
We are given the total number, and we want to find the number of tins and number in each tin now. So our equation looks like this.
56= cupcakes per tin • # of tins.
If we know that in 5 tins there are 35 cupcakes, and each tin has the same number we can divide 35 by 5 to find out there are 7 cupcakes in each tin. Now we have more info for our equation.
56 = 7 • # of tins.
We can divide the total number by the number in each tin, 56/7= 8.
Your answer is 8 tins.

The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
The answer is simply "8".
