Simplify 8a − 2a.(1

Answer 1

To simplify the expression 8a - 2a(1), we can distribute the 2a to each term within the parentheses:

8a - 2a(1) is equivalent to 8a - 2a * 1.

Multiplying 2a and 1 gives us 2a.

Therefore, 8a - 2a(1) simplifies to 8a - 2a which can be further simplified by combining like terms to 6a.

Answer 2

Simplify 12e − 5f − 7e +3f.

Answer 3

To simplify 12e - 5f - 7e + 3f, we first group the like terms:

(12e - 7e) + (-5f + 3f)

Combining the e terms, we get:

5e + (-5f + 3f)

And combining the f terms, we get:

5e - 2f

Therefore, 12e - 5f - 7e + 3f simplifies to 5e - 2f.

Answer 4

Simplify 9x + 3y − 6 − 5x + 4y −3.

Answer 5

To simplify 9x + 3y - 6 - 5x + 4y - 3, we first group the like terms:

(9x - 5x) + (3y + 4y) + (-6 - 3)

Combining the x terms, we get:

4x + (3y + 4y) + (-6 - 3)

And combining the y terms, we get:

4x + 7y + (-6 - 3)

Finally, combining the constant terms, we get:

4x + 7y - 9

Therefore, 9x + 3y - 6 - 5x + 4y - 3 simplifies to 4x + 7y - 9.

Answer 6

Simplify 9/11z − 4/11z.

Answer 7

To simplify 9/11z - 4/11z, we combine the like terms:

(9/11z - 4/11z)

When the denominators are the same, we can keep the same denominator and subtract the numerators:

(9 - 4) / 11z

Simplifying the numerator, we get:

5 / 11z

Therefore, 9/11z - 4/11z simplifies to 5/11z.

Answer 8

Simplify 3/10x + 1/6y + 3/10x + 3/6y. Be sure to reduce any fractions to the lowest terms.

Answer 9

To simplify 3/10x + 1/6y + 3/10x + 3/6y, we add the like terms:

(3/10x + 3/10x) + (1/6y + 3/6y)

Combining the x terms, we get:

(6/10x) + (1/6y + 3/6y)

And combining the y terms, we get:

(6/10x) + (4/6y)

Both fractions can be reduced.

Reducing 6/10, we divide the numerator and denominator by their greatest common divisor, which is 2:

(3/5x) + (4/6y)

Reducing 4/6, we divide the numerator and denominator by their greatest common divisor, which is 2:

(3/5x) + (2/3y)

Therefore, 3/10x + 1/6y + 3/10x + 3/6y simplifies to (3/5x) + (2/3y).
