Let's first turn all the words into numbers:
Two and four tenths = 2.4
One and six tenths = 1.6
Four and one tenth = 4.1
Now lets represent "a number" as x.
Then translate the wording into a linear equation:
Simplify and isolate the variable:
Divide by 0.8
x>1.375 or x>1 3/8
since each block is 3/8 of a mile, then how many miles in 4½? well, it'd just be their product, but let's firstly convert the mixed fraction to improper.
The distance between Mary and Rogers houses is 2.47 miles.
<u>Step-by-step explanation:</u>
From the given information we can form a right angle triangle.
Refer to the image given below.
N mentions the north and W mentions the south.
S denoted the School.
M denotes Mary's home - 2.1 miles away from School and forms one side of the triangle.
R denotes Roger's home - 1.3 miles away from School and forms another side of the triangle.
The distance between their houses will be the hypotenuse side of the triangle.
Hypotenuse side = .
= .
= .
=.
= 2.47.
Distance between their houses =2.47 miles.
