27, you multily eacg number by 3. 3*1=3, 3*3=9, 9*3=27, 27*3=81.
Hello, right answer is B) twice the original number
If you divide a number for a fraction, you are multiplying that number for the opposite of that fraction (so 1/2 = 2)
This means 4 : 1/2 = 4*2 = 8
Instead, if you multiply a number for 1/2, you are dividing it for 2.
Hope it helps :)
Answer:
b
Step-by-step explanation:
-a-(a-b)
Distribute the negative sign to get -a+a+b
-a cancels out a, and you're left with b.
The dilation factor for the question should be 1/2 as per options
So
dilated lengths are
- 2(1/2)=1in
- 4/2=2in
- 1/2=0.5in
- 5/2=2.5in
