2x + 3y = 40
-2x + 2y = 20
These are set up so we can just add them for the solution:
5y = 60
y = 12
2y-20=2x
x=y-10=2
Answer: x=2, y=12
Answer:
0 =n
Step-by-step explanation:
2 − 10n = 2 + 4n
Add 10n to each side
2 − 10n+10n = 2 + 4n+ 10n
2 = 2 + 16n
Subtract 2 from each side
2-2 = 2+16n-2
0 = 16n
Divide each side by 16
0/16 = 16n/16
0 =n
Answer:
no
Step-by-step explanation:
2^6=64
4^4=256

John's. Find the first common multiple of both denominators, in this case it's going to be ten, then the number you had to multiply to change these numbers to the common multiply you do to the numerators. so it works out like so:
Deena has a bottle of 4/10
John has a bottle of 25/10 or 2 1/2 (simplified)
