Solution
The correct option is A 4.5 Given:
Distance from home to school = 5 miles
Distance traveled by bus = 54miles
Distance traveled by car = 2.5x3
Total distance = Sum of the distance covered by bus and that by car
5=54+2.5x3
5=5×3+(2.5x×4)12LCM of 3, 4 is 12
By multiplying 12 on both sides, we get:
5×12=15+10x
60=15+10x
By subtracting 15 on both sides of the equation, we get:
60−15=10x
45=10x
Upon dividing by 10 on both sides, we get:
x=4510
x=4.5
Therefore, the value of x in the given equation is 4.5.
