Answer:
Step-by-step explanation:
Let the initial number be x
<u>Sold 1/3x, and now has:</u>
<u>Bought 84 more and now got 178:</u>
- 2/3x + 84 = 178
- 2/3x = 94
- x = 94 ÷ 2/3
- x = 94 × 3/2
- x = 141

Answer:
assuming we are multiplying 1/7 * w then w = 7/2 or 3 and 1/2
Step-by-step explanation:
Answer:
The dimensions are 6 by 5 feet.
Length = 6 feet.
Width = 5 feet.
Step-by-step explanation:
Let the length = L
Let the width = W
Perimeter of a rectangle = 2L + 2W
Translating the word problem into an algebraic equation, we have;
L = 2W - 4 ........equation 1
22 = 2L + 2W .......equation 2
Substituting the value of "L" into equation 2, we have;
22 = 2(2W - 4) + 2W
22 = 4W - 8 + 2W
22 + 8 = 6W
30 = 6W
W = 30/6
Width, W = 5 feet.
To find the length, L
Substituting the value of "W" into equation 1, we have;
L = 2W - 4
L = 2(5) - 4
L = 10-4
Length, L =6 feet
Therefore, the dimensions of the garden are 6 by 5 feet.
