Which expressions are equivalent to <br><br> 2 ln a + 2 ln b - ln a?
ycow [4]

Answer:

Choices 2, 3, and 5  are correct.

Step-by-step explanation:

Complete question is:

Check all that apply.

1. ln ab² - ln a

2. ln a + 2 ln b  

3. ln a² + ln b² - ln a

4. 2 ln ab

5. ln ab²

ANSWER:

The given expression is : 2 ln a + 2 ln b - ln a

It simplifies to: ln a + ln b² = ln ab²

Checking the given options.

1. ln ab² - ln a   = ln (ab²)/a = ln b²

  FALSE

2. ln a + 2 ln b = ln ab²

  TRUE

3. ln a² + ln b² - ln a = ln (a²b²)/a = ln ab²

  TRUE

4. 2 ln ab = ln a²b²

  FALSE

5. ln ab²

  TRUE

Jose can read 7 pages of his book in5 minutes. at this rate, how long will it take him to read the entire 175-page book?
Lera25 [3.4K]
Since 7 pages could be in 5 min.
So time required by 1 page 5/7 min.
So time required by 175 pages =175×5/7=125 min.
= 2 hours and 5minutes

can some one explain to me how fractions work who ever explains it well gets brainliest, adding, subtracting, multiplying, divid
Ludmilka [50]
Adding: When adding fractions, you want to make sure that the denominator is the same for both fractions. If they are already the same, just add both the numerators to get the answer. For example,
\frac{3 }{5}  +  \frac{1}{5}  =  \frac{4}{5}
If the denominator is different in both fractions, you have to find the least common denominator, or LCD. The LCD is the smallest number that both denominators can multiply into. For example, say you need to find
\frac{1}{6}  +  \frac{1}{3}

Multiply both the numerator and the denominator of (1/3) by 2 to get (2/6). This way, the denominators are the same and you can find the answer.
\frac{1}{6}  +  \frac{2}{6}  =  \frac{3}{6}
In the case that one denominator does not go into the other, find the smallest number they both multiply into. For example,
\frac{1}{3 }  +  \frac{1}{4}
Here, the smallest number that both 4 and 3 multiply into is 12. Multiply both fractions by the correct amount to make both denominators 12. It would then become
\frac{4}{12}  +  \frac{3}{12}  =  \frac{7}{12}
Subtraction: follow the same rules as addition, except subtract the numerators instead of adding them.

Multiplication: multiply both numerators and both denominators.
\frac{2}{3}  \times  \frac{4}{5}  =  \frac{8}{15}
Division: Flip one of the fractions and multiply.
\frac{2}{3}   \div   \frac{4}{5}
Becomes
\frac{2}{3}  \times  \frac{5}{4}  =  \frac{10}{12}  =  \frac{5}{6}
Hope this explains it all. Let me know if you have any questions :)

PLEASE HELP ME LIKE RN THIS IS 7TH GRADE MATH BTW
natulia [17]

Answer:

for the third one 2/5 for the fourth one 3/5

Step-by-step explanation:

For the first one, I put 10/25 as a fraction and found the least common multiple, which is 5. I then simplified, and got 2/5.

For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.

hope this helps if it doesn't I will correct myself :)
