Answer:

y has the greatest value.

Step-by-step explanation:

1.23w = t

Divide both sides by 1.23.

$w=\frac{t}{1.23}$

$w=0.813t$ --- (1)

1.01x = t

Divide both sides by 1.01.

$x=\frac{t}{1.01}$

$x=0.99t$ --- (2)

0.99y = t

Divide both sides by 0.99.

$y=\frac{t}{0.99}$

$y=1.01t$ --- (3)

From (1), (2) and (3), it is clear that y has the greatest value.

What is the solution of StartRoot x + 12 EndRoot = x?

Ber [7]

Answer:

x = 4 or x = -3

Step-by-step explanation:

$\sqrt{x+12}=x$

Take square both the sides,

$(\sqrt{x+12})^{2}=x^{2}\\\\x+12=x^{2}$

x² - x - 12 = 0

x² - 4x + 3x - 3*4 =0

x*(x - 4) + 3*(x - 4)= 0

(x- 4 )(x+3) =0

x -4 =0 or x + 3 = 0

x = 4 or x = -3
