A triangle has the following side lengths: x - 2, x, and 3x + 1. Another triangle has the following side lengths: 2x - 5, x + 4,

notka56 [123]

we know that

Perimeter of a triangle is equal to

P=a+b+c

where

a,b and c are the length sides of the triangle

<u>Find the perimeter of the triangles</u>

<u>Triangle N 1</u>

P=(x-2)+(x)+(3x+1)-------> P=5x-1

<u>Triangle N 2</u>

P=(2x-5)+(x+4)+(6x-7)------> P=9x-8

equate the perimeters

5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7

x=7/4------> x=1.75

therefore

the answer is

x=1.75

solve for x and y ,32base x+51base y and 23base x +42 base y =710. ,number bases interms of simultaneous equation

In-s [12.5K]

Answer:

Step-by-step explanation:

32base x means $3x + 2$

Similarly, 32base x+51base y equals to $3x + 2 + 5y + 1 = 3x + 5y + 3$

and 23base x +42 base y means $2x + 3 + 4y + 2 = 2x + 4y + 5$

As per the given condition, $3x + 5y + 3 = 2x + 4y + 5\\x + y = 2$

Putting, $y = 2 - x$ in $2x + 4y + 5 = 710$ , we get

$2x + 4y = 705\\2x + 4(2 - x) = 705\\8 - 2x = 705\\4 - x = 352.5\\x = -348.5$

$y = 2 - x = 2 - (-348.5) = 2 + 348.5 = 350.5$
