8 0

Answer: 8

Step-by-step explanation:

I recently had the exact same question on an exam, so I am assuming you have the same numbers.

AE = 6

BE = 4

DE = 3

To start, label the diagram appropriately.

As for CE, you need to put a variable, let's say x, since you don't now the number.

Next, apply the circle rule that states the necessary formula for this problem.

Since there are two lines stretching from one end to the next of the circle, you multiply one number from the opposite.

AE = 6 and BE = 4, so multiplying the two gets you 24.

This means that DE multiplied by x is also 24.

If DE = 3, divide 24 / 3 to isolate the variable.

Once you do this, you get 8 on one side, and x on the other. X, or CE, is 8.

Answer:

Step-by-step explanation:

2x – 5x + 16 = –3(x – 6)

2x - 5x + 16 = -3x + 18

Helen [10]

Answer:

2/6

Step-by-step explanation:

Each of the rectangle strips are taped together to form a rectangle. Therefore 1 of the third of the rectangle would be red, this means that 1/3 of the rectangle would be red color. The rectangle is then divide into sixths, this can be achieved by dividing each of the taped strip into 2.

Therefore 2 of the sixths rectangle would be red in color, Hence the fraction of the rectangle that would be red is given as 2/6
