Hello there,

<span>How do i substitute y=x to 3x+2y=20

Answer : since both are equal , you can change the letters to the same one.
3x + 2x = 20
5x = 20
x = 5
Therefore y = 5

Hope This Helps You!
Good Luck Studying :)</span>

Find the length of segment x. If necessary, round your answer to the nearest tenth (1 decimal place).

sineoko [7]

The length of the segment x is 16.2

Step-by-step explanation:

Here apply the Pythagorean relationship which states that the sum of squares of the sides is equal to the square of the hypotenuse.

Mathematically,

a²+b²=c²

where a=15, b=6, c=r

Hence;

15²+6²=c²

225+36=c²

√261=c

16.16

x⇒16.2
