Answer:
6 hours
Step-by-step explanation:
Given that:
Time taken by Sam = 3 hours
Sam's rate = 1/3
Time taken : Sam + Laura = 2 hours
Sam's rate + Laura's rate = 1/2
Let time taken by Laura = x
1/3 + 1/x = 1/2
1/x = 1/2 - 1/3
1/x = (3 - 2) / 6
1/x = 1 /6
x = 6
Hencw, it will take 6 hours for Laura alone to rake leaves
4 Triangles 1/2(6)6()= 18 18x4= 72
5 squares 3X3=9. 5x9= 45
72+45= 117 sq in

The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the temperature in Melbourne.
The highest temperature ever recorded there was 109°F, hence x ≤ 109°F.
Also, the lowest temperature ever recorded there was 20°F, hence x ≥ 20.
From both statements:
20°F ≤ x ≤ 100°F
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
