What do you need help with? I'm looking for points mate..
Answer:
12 fives and 18 tens
Step-by-step explanation:
solving this we need 2 different equations
one for he total bills and one for the total money
x+y=30
that is total bills
5x+10y=240
combining both equations we can use elimination method and get
12 five dollar bills and 18 ten dollar bills
2(x + y) + 3(x + y)
first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y
your answer is: 5x + 5y
hope this helps
Awnser is C. Random cuz thats how i chose this answer... its was random
Answer: a,b, and c are the correct solutions
Step-by-step explanation:
You are substituting each (x,y) for the equation given. They must equal the same on both sides.
