V=vanila
c=chocolate
4v+1c=45
v+c=27
mulitply 2nd equation by -1 and add to top one
-v-c=-27
<u>4v+1c=45 +</u>
<u />3v+0c=18
3v=18
divide by 3
v=6
sub back
v+c=27
6+c=27
c=21
21 choc and 6 van
A.
v+c=27
4v+1c=45
v=number of vanila wafers bought
c=number of chocolate wafers bought
B. 21 chocolate and 7
I got the answer with math because math is fun and tada
Answer:
23
Step-by-step explanation:
The question gives the first equation:
0.05N + 0.10D = 2.20
It can be rewritten as:
0.05$ times the number of nickels plus 0.10$ times the number of dimes is equivalent to $2.20.
Notice that 0.05$ or 5 cents is equivalent to one nickel and 0.10$ or 10 cents is equivalent to one dime.
The question asks for N+D. We know that N stands for the number of nickels Daniel has and D stands for the number of dimes Daniel has. We also know that Daniel <u>only</u> has dimes and nickels in his pocket. Therefore N+D most be equivalent to the <u>total number of coins</u>, which is given in the question to be equal to 23 coins.
Therefore...
N+D = 23
I believe it’s The domain of the function is all real numbers less than or equal to -2
Answer:
m = (2 - 5) / (2 - 0) = -3/2 = -1.5
Rational numbers are always natural numbers
