Answer:

x = 7

Step-by-step explanation:

3x - (1/9)y = 18

*subsitute y as 27, because they are equal to each other*

3x - (1/9)(27) = 18

*multiply and simplify)

3x - (27/9) = 18

*isolate x*

3x - 3 = 18

3x = 21

Pleasee help me, I don’t get it
Aleks [24]

Answer:

x = 4 sqrt(5)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

8^2 + x^2 = 12^2

64+ x^2 =144

Subtract 64 from each side

x^2 = 144-64

x^2 =80

Take the square root of each side

sqrt(x^2) = sqrt(80)

x = sqrt(16*5)

x = 4 sqrt(5)
