An expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. The value of x makes this proportion true 3/x=15/40 is 8.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A ratio shows us the number of times a number contains another number. The value of x in the given expression can be found using the ratios. Therefore, The value of x makes this proportion true 3/x=15/40 is,
3 / x = 15 / 40
3 × 40 = x × 15
120 = 15x
x = 120/15
x = 8
Hence, The value of x makes this proportion true 3/x=15/40 is 8.

Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins
