1) The normal room temperature is said to be about 20°C
2) 5 day is equivalent to 120 hr
3) 756 m³/s is equivalent 56000 L/s
4) It would take the snail 5 hours to crawl 75 m
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
1) The normal room temperature is said to be about 20°C
2) 1 day = 24 hr
5 day = 5 day * 24 hr per day = 120 hr
3) 1 m³ = 1000 L
756 m³/s = 56 m³/s * 1000 L/m³ = 56000 L/s
4) 1 m = 100 cm
75 m = 7500 cm
Time = 7500 / (25 cm/min) = 300 min = 5 hours

Answer:
The correct answer is
(x + 2) (x + 1) (x - 3)
Step-by-step explanation:
15.
0.20*x = 0.01*x + 38 => 0.19*x = 38 =>( 19/100 )*x = 38 => x = 3800/19 => x = 200.
Answer:
Number of children, x= 400
Number of adults, y = 100
Step-by-step explanation:
Let the number of children be x
Let the number of adults be y
Given : Total number of people, x + y = 500 --------(1)
Total amount collected, 5x + 10y = 3000 ---------(2)
(1) => y = 500 - x
Substitute y in (2) : 5x + 10(500 - x) = 3000
5x + 5000 - 10x = 3000
-5x = 3000 - 5000
-5x = -2000
x = 400
Substitute x in (1) : 400 + y = 500
y = 500 - 400
y = 100
