What’s x Pythagorean triples

nadezda [96]

We have to find x and x is the hypotenuse. We use this formula:

hyp²=side²+side²

So:

hyp²=side²+side²

hyp²= 12²+9²

hyp²= 225

hyp²= √225

hyp= 15

Therefore, the hypotenuse is 15 and x is 15.
HOPE THIS HELPS!

Wich equation gives the number of 1/3 inches that are in 5/6 inches

lara31 [8.8K]

Hello from MrBillDoesMath!

Answer:

(1/3) x = (5/6)

Discussion:

I think you are asking for this equation:

(1/3) x = (5/6) => multiply both sides by 3

(1/3) 3 x = (5/6) 3 => as (1/3) *3 = 1

x = 5*3/6

x= 15/6

x = 5/2 = 2.5

Thank you,

MrB

Help....!! I need to solve this simultaneous equation y=x-2 and y=3x+5 With working out if possible please....

Blababa [14]

Step-by-step explanation:

Y= x - 2. Y = 3x + 5

Putting value of y

x - 2 = 3x + 5

-2 - 5 = 3x - x

-7 = 2x

-7/2 = x

Putting value of x

Y = 3(-7/2) + 5

Y = - 10.5 + 5

Y = - 5.5
