Answer: 1, 4, -7
Step-by-step explanation:
Coefficients are numbers that are in front of a variable. Let's first determine the terms that have variables in them.
z, 4z², -7a
Since these all have variables in the terms, we know the coefficients are 1, 4, -7.
Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service.
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%).
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.
<span>mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you
can only add like terms( like terms are terms that are same name like x
or y are differnt, and like terms have same power exg x^2 and x^3 and
x^1/2 and such
I will oly put the naswers because I don't have much time
first one: 2a+3b+2c
second one: remember that -(-6c)=+6c so the answer is c-10a-2b
third one: -a-8b-5c
