Answer:

3

Step-by-step explanation:

Let's try 4 first.

4^8 is 65536, and 4^5 is 1024.

65536 / 1024 is 64, so 4 is not an answer.

And, let's try 3.

3^8 is 6561, and 3^5 is 243.

6561 / 243 is 27, so 3 is the answer!

Points A, B, and C are collinear. Point B is between A and C. Find the length indicated. AB= 5x-15, BC=3x-5, and AC=28. Find AB
katrin2010 [14]

Answer: AB is 15

Step-by-step explanation: First, you need to draw a picture and label the parts of the line: AB=5x-15; BC= 3x-5; AC =28. Because of the segment addition postulate, you set the equation to be 5x-15+3x-5=28. Then you solve:

5x-15+3x-5=28

Add like terms:

8x-20=28

Add 20 to both sides

8x=48

Divide by 8

x=6

Now, you need to find the measure of AB, so you plug the 6 into the x variable for 5x-15

5(6)-15

30-15

AB=15

Karen will divide her garden into equal parts. She will plant corn in 8/20 of the garden what is the fewest number of parts she
gayaneshka [121]

Answer:

5

Step-by-step explanation:

We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.

This implies that she divide the garden was divided into 20 parts.

To determine the fewer number of parts she can divide her garden into, simply ⁸/20.

Thus:

8/20 = (2*4)/(5*4)

= ²/5 (4 cancels out 4)

Therefore, this implies that the least number of parts she can divide her garden into is 5.
