Answer:
The dimensions of the garden is 21.5 ft by 114.5 ft
Step-by-step explanation:
Here, we want to find the dimensions of a rectangular garden.
From the question, we are told that the length is 7 feet more than 5 times the width.
Let the length be l and the width be w;
Thus, mathematically;
l - 7 = 5w
l = 5w + 7
Mathematically;
Perimeter of rectangle = 2(l + w)
Hence;
2(l + w) = 272
divide both sides by 2
l + w = 136
but l = 7 + 5w
7 + 5w + w = 136
7 + 6w = 136
6w = 136-7
6w = 129
w = 129/6
w = 21.5 ft
But,
l = 5w + 7
l = 5(21.5) + 7
l = 114.5 ft
Answer:
Achmed has 7 pencils.
Step-by-step explanation:
Let Achmed have x pencils, then:
Gloria has 2x pencils and Peng has 3x pencils so we have the equation:
x + 2x + 3x = 42
6x = 42
x = 7.
Achmed has 7 pencils.
