If X is -1 then sub and it will equal -5
Answer:
<em>10</em>
Step-by-step explanation:
<em>To solve this, we have to do 4 divided by 2/5, because there are stops every 2/5 mile of a 4-mile track.</em>
<em>To make dividing easier, you can write 4 as a fraction, which would be 4/1</em>
<em>Now, divide:</em>
<em>4/1 ÷ 2/5</em>
<em>Remember that when you divide a fraction by another fraction, you can multiply the first fraction by the reciprocal of the second fraction and get the same fraction.</em>
<em>The reciprocal of 2/5 is 5/2.</em>
<em>So 4/1 x 5/2 = 20/2, which can be simplified as 10.</em>
<em>So there are 10 stops. </em>^-^

(b) Mara's rectangle
Step-by-step explanation:
Given
Mara
Ashton
Solving (a): Draw the rectangles
First, we need to calculate the possible dimension of both rectangles.
Area is calculated as:
For Mara
Possible values of length and width are:
This is so because:
For Ashton
Possible values of length and width are:
This is so because:
<em>See attachment for diagram</em>
Solving (b): Rectangle with bigger area
Mara's rectangle has a bigger area because
