Multiply the first number by 0.032 then add it to the first number and that will be your answer

15x - 30 = 10x + 5
15x - 10x -30 = 5
5x - 30 = 5
5x = 5 + 30
5x = 35
Divise by 5 on both sides to isolate x
x = 7 => answer

Answer:

6.32

Step-by-step explanation:

To find the side length on a right angled triangle we follow The Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

c being the hypothesis (longest side: the hypotenuse is always opposite the right angle)

so..

${6}^{2} + {2}^{2} = {x}^{2} \\ 36 + 4 = {x}^{2} \\ 40 = {x}^{2} \\ \sqrt{40} = \sqrt{ {x}^{2} } \\$

$6.32 = x$
