Answer:
3+18=21
Step-by-step explanation:
first see the second number
let us assume as x & y
3+ (3×6)= 21
3+18=21
Store A
50*5%=2.5
50-2.5=47.5
47.5+(6%*47.5)=$50.35
Store B
20%*60=12
60-12=48
48+(6%*48)=$50.88
I would but the watch from store A because it would be 53 cents cheaper.
Answer:
Infinite solutions
Step-by-step explanation:
x + y = 10
y = -x + 10
We'll choose one equation to use, x + y = 10
Substitute y with -x + 10
x - x + 10 = 10
x cancels each other out
10 = 10, which would also mean 0 = 0
This means the answer will validate with any number
