well, the sequence goes, 1100, to 1135, to 1170.... notice, is simply adding 35 to get the next term, so the common difference is 35, and the first term is 1100 of course.

Answer:
5 is the coefficent of y if you simplify and 3 is the constant
Step-by-step explanation:
7y-2y=5y. The coefficient is the number that goes with the variable, or letter, such as y. The constant is the number that does not have any coefficients attached to it.
Step-by-step explanation:
There are 4 cards less than or equal to 4.
1/6 = 4/n
n = 24
Answer:
6x−11y+15
Step-by-step explanation:
Distribute the Negative Sign:
=5x−6y+7+−1(−x+5y−8)
=5x+−6y+7+−1(−x)+−1(5y)+(−1)(−8)
=5x+−6y+7+x+−5y+8
Combine Like Terms:
=5x+−6y+7+x+−5y+8
=(5x+x)+(−6y+−5y)+(7+8)
=6x+−11y+15
Answer:
6x−11y+15
I hope I helped!!
