Ashton and Kamir are arguing about how a number trick they heard goes. Ashton tells Andrew to think of a number, multiply it by

Artemon [7]

Answer: The number was 9.

Step-by-step explanation:

Let the number be 'x;.

think of a number, multiply it by five and subtract three from the result :

According to Ashton, the expression would be :

$5x-3$

Kamir tells Andrew to think of a number, add five and multiply the result by three:

According to Kamir, the expression would be :

$3(x+5)$

At last, they get the same number :

$5x-3=3(x+5)\\\\5x-3=3x+15\\\\5x-3x=15+3\\\\2x=18\\\\x=\dfrac{18}{2}\\\\x=9$

Hence, the number was 9.

I need to know how to solve this (Pythagorean theorem) and the answer

Neko [114]

Answer:

≈ 106.4

Step-by-step explanation:

Pythagorean Therorem: $a^{2} + b^{2} = c^{2}$

Equation: $28^{2} + b^{2} = 110^{2}$

$784 + b^{2} = 12100$

-784 -784

$b^{2} = 11316$

$\sqrt{b^{2} } = \sqrt{11316}$

= 106.3766892

Round to nearest tenth:

≈ 106.4
