Answer:
2.0 x
Step-by-step explanation:
1. length = 3.2 x m
width = 1.6 x m
Area of a rectangle = length x width
= (3.2 x ) x (1.6 x
)
= 5.12 x
2. length = 1.28 x m
width = 8 x m
Area of a rectangle = length x width
= (1.28 x ) x (8 x
)
= 1.024 x
=
= 20
= 2.0 x
Thus,
The area of rectangle 2 is 2.0 x times greater than the area of rectangle 1.
For this case we must write a situation for the following inequality:
Andres needs less than $200 to go on vacation. It is known that in his work he earns $12 per hour, he must also pay a debt of $14. We want to know how many days he gets less than $200. Assuming Andres works 8 hours a day.
x: Variable that represents the number of hours Andres works
Thus, Andres must work less than 17.83 hours for his trip.
Therefore, it requires three work days.
