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
M = 6w - 31
m + w < 11
6w - 31 + w < 11
7w - 31 < 11
7w < 11 + 31
7w < 42
w < 42/7
w < 6
oldest age warren can be is 5...but I do not see how that is possibly because if warren is 5, then marty is : 6(5) - 31= 30 - 31 = -1
unless u make warrens age 5 1/2....making warrens age 2...wait, that wont work because u need a whole number
A dozen is 12, and so 2.5 dozen is 30, so 30 muffins require 1.25 cups of flour, so it should be 5 cups of flour for 10 dozen muffins.
