You can simplify expressions by simplifying parentheses by using the distributive property and combing like terms.
Combining like terms is the process of adding up numbers with the same variable(s) and exponent. If a term does not have an exponent then an exponent of 1 is implied.
There is no parentheses in the expression 3a + 7 - a - 7
But, there are like terms in the expression.
Which are the like terms?
3a and a are both like terms. They both have the same variables and they both have the same exponent.
7 and -7 are like terms, too.
3a + 7 - a - 7
2a
So, 2a is the simplified version.
Answer: 30
Step-by-step explanation: If you play 36 games in total but the ratio is 5:6 you could use a little dividing so 36/6 is 6 so you would multiply both number by six giving you 30:36
Answer:
an = 7 + 5n
Step-by-step explanation:
First we know that for each number of days rented the cost increase by 5 so we get an - (?) + 5n.
We also know the first number is 12 for 1 day, so for 0 days, or the starter cost, is 7. We get this by subtracting 5 from 12.
Hence the answer an = 7 + 5n
Thank you for posting your question here at brainly. I hope my answer will help.
Since the midpoint of a line segment ZP is A and XY = ZA therefore XY is equal also to AP as midpoint <span>divides a line segment into two equal segments. For example the total length of line segment is 10" then to get the midpoint you divide with to so the midpoint is in 5".</span>
