Step-by-step explanation:
Given
The actual length of the parking lot is 75 m
length in the drawing is 135 cm
Here, 75 m is equivalent to 135 cm
Using unitary method



<u><em>Answer:</em></u>
(m×1/3)-6=y
<u><em>Step-by-step explanation:</em></u>
- Start with m as the unknown variable.
- Now multiple that by 1/3 to find that portion of m. (m×1/3)
- Lastly, subtract 6 and set the expression equal to y. (-6=y)
- Thus we get our final equation: (m×1/3)-6=y

The full road trip is 50 miles.
Step-by-step explanation:
Given,
Distance traveled by Joe's family = 30 miles
This represents 60% of the total distance to be traveled.
Let,
x be the total distance.
60% of x = 30

Dividing both sides by 0.6

The full road trip is 50 miles.
