Answer:
a)7/4= n/12
21=n
b) 8+4y=6
4y=-2
y=-1/2
Step-by-step explanation:
1/2(8x -2) + ( -2x + 1/4)
(4x -1) + (-2x + 1/4)
=
(2x - 3/4) or (2x - 0.75)

Answer:
x = 4
Step-by-step explanation:
Divide by 2, subtract 8 ...
2(4/x +8) = 18
4/x +8 = 9
4/x = 1
4 = x . . . . . multiply by x
Answer:
2(b+1+b)= 18
Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
18 feet= 2(l+b)
length: l, breadth: b
Because the length of the sandbox is 1 foot longer, it will be:
b+1 = l
Substitute l with b+1
2(b+1+b)= 18
