The length of a DNA nucleotide building block is about 1 nanometer, or 0.000000001 meters. Fill in the blank to write this number in scientific notation.
×10−9
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x."
Answer:
B. x < 5
Step-by-step explanation:
Lets go first with 3x – 8 < 23 then with - 4x + 26 > 6 and after that we put them together. (I will use the < > signs but as I see on the pictures these include the =, being less and greater OR equal).
3x – 8 < 23
Lets sum 8 in both sides:
3x < 23 +8
3x < 31
Now, divide both sides by 3:
3x/3 < 31/3
x < 31/3
Here we found one condition. Lets go with the other inequality for the other condition:
- 4x + 26 > 6
Lest sum 4x in both sides to get a potive x:
- 4x + 26 + 4x > 6 +4x
26 > 6 +4x
Now subtract 6 in both sides
26 - 6 > 6 +4x - 6
20 > 4x
Finally, divide both sides by 4:
20/4 > x or 5 > x (simplifying we get the second)
So, our second condition says that x must be less than 5.
So, putting both conditions together:
x < 5
x < 31/3 = 10.33
So, if x must be less than 5 and less than 10.33, is the same that saying that x mus be less than 5. We con obviate the condition that x must be less than 10.33 as it is included in the other. So our answer is:
x < 5
It is the option B in the image (remember I didnt use the less or equal sign because you didn't included it in the statement).
Answer with explanation:
The given expression is
=ab+cd+ef+gh
The meaning of expression is equal to terms which contains variables and constants and operation between them is Addition, Subtraction, Multiplication and Division.
→The expression consists of four terms which are, ab, cd, ef, and gh.
→Each term contains
Two factors.
