X=6.6
Y=12
Finding x first using Pythagorean theorem and then y
Ok this is how it work:
1+4=5
2+5=12=2+1+4+5=12
3+6=21=12+3+6=21
8+11=? do the same to that take 21+8+11=40
ask me if you don't get it. I explain it further.
Answer:
y = 3x + 8
Step-by-step explanation:
Answer:
It took him 12 hours
Step-by-step explanation:
480 / 40=12
Simplify the following:
3 x + 2 y + x + 3 y
Grouping like terms, 3 x + 2 y + x + 3 y = (2 y + 3 y) + (3 x + x):
(2 y + 3 y) + (3 x + x)
2 y + 3 y = 5 y:
5 y + (3 x + x)
3 x + x = 4 x:
Answer: 5 y + 4 x
