Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out.
You said that you thought of number J, and then subtracted half of it from 34. This can be mathematically written as:
= 34 - (J/2)
Let's reframe the question and assume that you thought of a number J, and then subtracted half of it from 34 and the answer you get is 12. To find J goes thus:
You subtract half of J from 34 and equate it to 12. This will be:
34 - (J/2) = 12
Collect like terms
34 - 12 = J/2
22 = J/2
J = 22 × 2
J = 44
In this scenario, J = 44. We can check to confirm.
Check: 34 - (J/2)
= 34 - (44/2)
= 34 - 22
= 12
Answer:
The difference is 6.74 * 10^-3 centimeters
Step-by-step explanation:
Firstly, we need to write the numbers as they would occur normally
we have this as;
7.65 * 10^-3 = 0.00765
9.1 * 10^-4 = 0.00091
So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number
we have this as;
0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters
5. Five: A ray has one endpoint and extends indefinitely in one direction. A pair of opposite rays are two rays that have the same endpoint and extend in opposite directions. Rays are always named with two points and the first point in the name must be the endpoint.
