Answer:
x = 3
Step-by-step explanation:
=> 4x-5x+9=5x-9
=> -x-5x = -9-9
=> -6x = -18
=> x = 18/6
=> x = 3
Answer:
30
Step-by-step explanation:
If you plug in 5 for x and 3 for y then the equation would be 3(5)+5(3) or 15+15.
w + 4
------------------------
l l
l l w
l l
------------------------
Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14
