To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y
Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250
The lines that intersect is B
Answer:
Step-by-step explanation:
225-9x=v
225-9(7)=v
225-63=v
162=v
your answer is A
It is
If you have a slope (which is before the x) then it’s a linear equation
