An equivalent expression for 9z+27

Answers

Answer 1
Answer:

Answer:

=9(z+3)

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you had to rewrite the problem down of 27=9*3

9z+9*3

Then, you can also factor it out by the common term of 9.

=9(z+3)

Hope this helps!

Thanks!

Answer 2
Answer:

Final answer:

The equivalent expression for 9z+27 is 9(z+3). By factoring out the greatest common factor, we can simplify the expression and represent it in a different form. For example, if z=5, then the original expression 9z+27 is equal to 72, which is also the value of the equivalent expression 9(z+3).

Explanation:

The equivalent expression for 9z+27 is 9(z+3).

To find the equivalent expression, we can factor out the greatest common factor of the terms, which in this case is 9. We can rewrite the expression as 9(z+3), where z+3 represents the remaining terms after factoring out 9.

For example, if z=5, then the original expression 9z+27 becomes 9(5)+27 = 45+27 = 72, and the equivalent expression 9(z+3) also becomes 9(5+3) = 72.

In need to know the answer of 12z+18 in distributive property

Answers

Answer:

6(2z + 3)

Step-by-step explanation:

Step 1:  Find the GCF

12 → 1, 2, 3, 4, 6, 12

18 → 1, 2, 3, 6, 9, 18

The GCF is 6

Step 2:  Pull out the GCF

12z + 18

6(2z + 3)

Answer: 6(2z + 3)

Answer: 6(2z + 3)

Step-by-step explanation:

So, with the distributive factor you want to find the greatest common factor. In this case, the greatest common factor is 6 because it can go into both 12 and 18. So now you need to simplify the numbers. You would put the 6 on the outside because it is the GFC.

6(

Now, you need to divide both numbers by 6 and your equation should look like this:

6(2z +3)

Ariel goes running for 5/6 of an hour.The next day,she runs for 3/4 as much time. Does she spend more or less time running the second day? Draw a diagram or make a model to represent the problem.

Answers

less because 3 fourths is more than 5 sixths

Answer:

Less

Step-by-step explanation:

Less time because you first find the common denominator which is twelve for 3/4 it would be 9/12 and for 5/6 it would be 10/12 so 5/6 which is greater that 3/4.

Which problems result in a positive number? Choose all answers that are correct. A. –4.6 • 1.6 B. –10 • (–5.2) C. 8.4 ÷ 2 D.

Answers

Well you can automatically eliminate, A, because when you multiply one number that's positive and another number that's negative the result is always going to be negative.
However, when you multiply two negatives the result is always positive!

So, the only ones up there that would result in a positive number is B and C

***D. was not posted so I cannot determine that one!

After how many years are the salaries offered by company b and c the same?

Answers

A and B
3000x + 24000 = 2400x + 30000
3000x - 2400x = 30000 - 24000
600x = 6000
x = 6000/600
x = 10 years A and B are the same

B and C
2400x + 30000 = 2000x + 36000
2400x - 2000x = 36000 - 30000
400x = 6000
x = 6000/400
x = 15 years B and C are the same
