Determine the digits of y from these clues. the digits of y add to 16. the first digit is 4 times the third digit. the second digit is 3 times the third digit. y is a three digit number.

The number Y is  862.

Step-by-step explanation:

Given : Y is a three digit number and the digits of Y add to 16 and The first digit is 4 times the third digit. The second digit is 3 times the third digit.

We have to find the number Y.

Since, Y is a three digit number

Let Y = abc , where a, b, c are the digits of Y.

According to given question ,

a + b + c = 16  (1)

also, The first digit is 4 times the third digit that is a = 4c  (2)

and, The second digit is 3 times the third digit that is b= 3c (3)

Substitute (2) and (3) in (1) , we get,

⇒ 4c + 3c + c = 16

⇒ 8c = 16

⇒ c = 2

Thus, c = 2

Put c = 2 in (2) and (3) to find a and b ,

thus,  a = 4c = 4(2) = 8

b = 3c = 3(2)= 6

Thus, number Y = abc = 862.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the answer is 1/4
