(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.
Answer:
The length of Ave's garden is 8 feet.
Step-by-step explanation:
The area of a rectangle can be calculated by:
A = l × w
Where; A represents the area, l the length and w, width.

32 = l × 4
l = 32 /4
l = 8
Therefore, the length of the garden required is 8 feet.
Answer:

Step-by-step explanation:
7-2x=2(x-4)-1
7-2x=2x-8-1
7-2x=2x-9
7+9=2x+2x
16=4x
x=4
