Seja E a expressão que queremos calcular:
The circumference of the top of the cake is
in.
It sounds like the baker is trying to line the circumference with cherriesto fit as many as possible along the border, like in the picture I've attached below.
This comes down to dividing the cake's circumference by the diameter of each cherry:

or about 39 cherries, making the answer D.
(x-4)•2 < 9
the difference between x and 4 means to subtract
and twice that means to double or times by 2
and all that’s LESS than 9
so the sign opens up towards the 9
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
Whats your problem I can help you, what type of problem is it?
