Answer:
32n = 100 - 20
n = 2.5
he purchased 2 sweaters
Step-by-step explanation:
32n = 100 - 20
If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20
Your equation is gonna be
4.5a + 2.5b = 4.25
I forgot how lol but you gotta now solve for A and B.
The probability that exactly 3 of the chosen sandwiches are turkey is; 0.004
<h3 /><h3>How to find the probability combination?</h3>
We are given;
Total number of sandwiches = 15
Number of sandwiches that were turkey = 6
Now, she selects 6 of the sandwiches and we want to find the probability that exactly 3 are turkey.
Now, number of ways of selecting 6 sandwiches is; 15C6
Number of ways of selecting 3 turkey's out of the 6 chosen is; 6C3
Thus, the probability that exactly 3 of the chosen sandwiches are turkey is; 6C3/15C6 = 20/5005 = 0.004

Mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
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
so first one
3b+11c-4c-c
since they are all c except for the first one term, just assign a number for each so it simplifies to c times(11-1)+b(3-4)=c(10-1b=10c-b or
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
second one9a-1+8c-8a+c
group like terms
(9a-8a)+(8c+c)-1=(a)+(9c)-1=a+9c-1
12c+5a+7-13c+4a
group like terms(12c-13c)+(5a+4a)+7
add like terms
-c+9a+7
the solution is 9a-c+7
-15-6c+3b-6c+9-2b
group like terms
(-15+9)+(-6c-6c)+(3b-2b)
-6+(-12c)+b=b-6-12c
the answers are:
10c-b
a+9c-1
9a-c+7
b-12c-6
The slope would be 2/7 in order for any line to be parallel to it.
