One number is one more than a second number. Five times the first is 3 less than 6 times the second. Find the numbers.
TiliK225 [7]

The value of the first number is 9 , and

the value of the second number is 8 .

In the question ,

statements about two numbers is given ,

let the first number be x ,

let the second number be y .

According to the first statement " One number is one more than a second number "

translating it into the equation form , we get

x=y+1      ...(i)

According to the second statement which states " Five times the first is 3 less than 6 times the second "

translating it into the equation form , we get

5*x = 6*y - 3

5x = 6y - 3

Substituting the value of x from equation (i) , we get

5(y+1) = 6y - 3

5y + 5 = 6y - 3

6y-5y = 5+3

y = 8 ,

substituting  y=8 in the the equation (i) ,

x = 8 + 1

x = 9

hence the first number = 9  and the second number = 8 .

Therefore , the value of the first number is  9, and

the value of the second number is 8 .

An insect crawls 30 inches in 16.3 minutes. If
omeli [17]

Answer:

Step-by-step explanation:

Convert 6 hours to minutes so that 6 hours and 16. 3 minutes can be in the same units.

Since 1 hour = 60 minutes, then 6 hours = 6 x 60 minutes = 360 minutes

Since the insect has more minutes to crawl (360 minutes), then we expect more inches to be covered. Therefore, the ratio is 360 minutes to 16.3 minutes

= 360 minutes : 16.3 minutes

= 360 : 16.3  

Now express the ratio as fraction and relate it with 30 inches

= 360/16.3  x  30/1

= 10800/16.3

= 662 .576687 and this is approximately 650 inches

Answer  = 650 = (C)
