Simplify 8a − 2a .(1 point)
The simplified expression is 6a.
Simplify 12e − 5f − 7e +3f .
The simplified expression is 5e - 2f.
Simplify 9x + 3y − 6 − 5x + 4y −3 .
To simplify the expression, we combine like terms:
(9x - 5x) + (3y + 4y) + (-6 - 3)
This simplifies to:
4x + 7y - 9
Simplify 9/11z − 4/11z .
To simplify the expression, we combine like terms:
(9/11z - 4/11z)
Since the denominators are the same, we can subtract the numerators:
(9 - 4)/11z
This simplifies to:
5/11z
Simplify 3/10x + 1/6y + 3/10x + 3/6y . Be sure to reduce any fractions to the lowest terms.(1 point)
$$
To simplify the expression, we combine like terms:
(3/10x + 3/10x) + (1/6y + 3/6y)
Simplifying each term separately:
6/10x + 4/6y
Reducing the fractions to lowest terms:
(3/5)x + (2/3)y
To simplify the expression 8a - 2a, you need to combine like terms.
Like terms are terms that have the same variable and exponent. In this case, both terms have the variable "a" with an exponent of 1, so they are like terms.
To combine the terms, simply subtract the coefficients of the like terms. In this case, 8a - 2a, the coefficient of "a" is 8 in the first term and -2 in the second term, so we subtract them:
8a - 2a = (8 - 2) * a
The result is 6a. So, the simplified expression is 6a.
