The larger of two numbers is four times the smaller number, and their difference is 18. Find the two numbers.

Mathematics
1 answer:
podryga [215]3 years ago

Answer:

x = 12 , y = 10

Step-by-step explanation:

Let x , y are two numbers.

x > y

1 ) Three times the greater is 18 times their

difference

3x = 18( x - y )

x = 6( x - y )

x = 6x - 6y

6y = 5x

y = 5x/6 ——-( 1 )

2 ) 4 times the smaller is 4 less than twice

the sum of the two

4y + 4 = 2 ( x + y )

2y + 2 = x + y

y = x -2 ——( 2 )

From ( 1 ) and ( 2 ) ,

5x/6 = x -2

( 5x /6 ) - x = -2

( 5x - 6x ) /6 = -2

-x = -12

x = 12

Put x = 12 in equation ( 2 ) , we get

y = 12 - 2

y = 10

Therefore ,

x = 12 , y = 10

Assume the method dosomething has been defined as follows: public static void dosomething (int[] values, int p1, int p2) { int t
Fudgin [204]
First step is to analyze input and output variables:
INPUT:
list of integers with name "values"
integer with name "p1"
integer with name "p2"
OUTPUT:
there is no output variable as in declaration of a method there is void

ANALYSIS:
"<span>int temp = values[p1]"
this line creates variable "temp" which is integer. then this line goes to the list "values" and takes value that is at position "p1" and stores it into variable "temp"

"</span><span>values[p1] = values[p2]"
this line </span>goes to the list "values" and takes value that is at position "p2" and stores it into variable that is at position "p1"

"<span>values[p2] = temp"
this line takes value of the variable "temp" and stores it into list values at position "p2"

Short explanation:
this code replaces values of the list at between positions p1 and p2</span>

A mutual fund rating agency ranks a​ fund's performance by using one to five stars. A​ one-star mutual fund is in the bottom​ 20
Paladinen [302]

Each star has a 20% difference.

A four star rating would be above the bottom 60% ( 1, 2 and 3 stars) but be below the top 20%. (5 stars).

The ideal weight of a nickel is 0.176 ounce. To check that there are 40 nickels in a roll, a bank weighs the roll and allows for
ludmilkaskok [199]

Answer:  Total weight will be 7.055 ounces.

Step-by-step explanation:

Since we have given that

Ideal weight of a nickel = 0.176 ounce

Number of nickels in a roll = 40

Total weight becomes

40\times 0.176\\\\=7.04\ ounces

Error that was allowed in total weight = 0.015 ounce

So, Total weight will be

Total\ weight=7.04+0.015\\\\=7.055\ ounce

Hence, Total weight will be 7.055 ounces.
