Step-by-step explanation:
Answer:
y = -4
Step-by-step explanation:
Once you recognize the line as being horizontal, you know its equation will be ...
y = (some constant)
The value of the constant will correspond to the y-coordinate of the points the line goes through. It will also be the value of the y-intercept. Here, that value is -4, so the equation is ...
y = -4
Okay so subtract 50 from both sides and you would get 360=90x and then divide each side by 90 and you would get x= 4 so it took 4 hours
Answer:
x=
Step-by-step explanation:
Exact Form:
x=
Decimal Form:
x=6.5
Mixed Number Form:
x=6
X+20+10x=20+9x
adding like terms
x(10+1)+20=20+9x
11x+20=9x+20
subtracting 9x from both sides
2x+20=20
subtracting 20 from both sides
2x=0
dividing by two for both sides
x=0
