Answer:
divide the previous value by 5
Step-by-step explanation:
5^2=25, 5^1=5, 25/5=5
Answer:
Question 1: answer is A because it collaborates with question 2, and Question 2 is B for it has not relation between input and output variables
2 inch is 10 miles
0.5 inch is 2.5 miles
so it is 12.5 square miles?
Let's call the bigger number n
So the smaller number is 2/5n
So n + 2/5n = 21
Which is equivalent of n + 2n/5 = 21
Then you need to get rid of the fraction by multiplying everything by 5
5n + 2n = 105
Or simply
7n = 105
Divide both sides by 7 to isolate n
n = 15
So the larger number is 15
Now we need to work out 2/5 of 15 to work out the smaller number
(15/5 [the denominator])*2 [the numerator] = 6
So the two numbers are 15 and 6
