Regan has already baked 18 cakes, and she can bake 1 cake with each additional stick of butter she buys. With 28 additional sticks of butter, how many total cakes can Regan bake?

46

Step-by-step explanation:

She has baked 18 cakes already

She buys 28 additonal sticks of butter, it takes one stick of butter to make a cake. 28 sticks of butter = 28 additonal cakes

 18 cakes- baked

+  

28 - cake can be baked with the 28 addtional sticks of utter

46 total cakes can be baked.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
