Answer:

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

the correct answer is 12k-8

Step-by-step explanation:

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11

No, the simplification is not done correctly. When multiplying

\frac{2}{3}\times-9 we should get -6 instead of -9.

Correcting the error:

\frac{2}{3}  (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8

So, the correct answer is 12k-8

Marina CMI [18]
Something I noticed about angle 4, is that it shares a straight line with angle 3. (above it is a straight line)

A straight line equals 180 degrees.

So, angle 4 + angle 3= 180 degrees.

Angle 3 is congruent to angle 7.

180-132= Angle 7

180-132= 48

48 degrees is your answer.

I hope this helps!

Karens batting average is 0.444.she was at bat 45 times. how many hits did she get
alexgriva [62]

Answer:

A batting average is simply the ratio of hits/at-bats.  So, if Karen were up to bat 1,000 times and she got a hit 444 times, that makes her batting average 444/1,000 = .444.

The good news is you can multiply this ratio by number of at bats to get the number of hits.

So, 45 hits x .444 = your answer.

Hope that helps.
