P=2(l+w)
50=2(4+w)
50=8+2w
collect the like terms 50-8=2w
42=2w divide both sides by 2
w=21
Step-by-step explanation:
The equation of the line is y = 4x - 9.
Answer:
y=3
Step-by-step explanation:
3x+2y=9
Let x =1
3*1+2y=9
3 +2y = 9
Subtract 3 from each side
3-3+2y=9-3
2y = 6
Divide each side by 2
2y/2 = 6/2
y =3
First you put 2.13 on top of a fraction and 36 on the bottom. Then you divide 36 by 2.13 and put the answer, 16.90, on top of another fraction and put a 1 on the bottom of that other fraction.
