2) For which value of P and W is P + W a rational number? P = 1/(sqrt(3)) And W = 1/(sqrt(6)) 2) P = 1/(sqrt(4)) and w = 1/(sqrt

fenix001 [56]

Answer:

P = 1/(sqrt(4)) and w = 1/(sqrt(9))

Step-by-step explanation:

Only the roots of perfect squares are rational numbers. 2, 3, 6, and 10 are not perfect squares, so their roots are irrational. Both 4 and 9 are perfect squares, so their roots are rational. The sum of rational numbers is a rational number.

$\dfrac{1}{\sqrt{4}}+\dfrac{1}{\sqrt{9}}=\dfrac{1}{2}+\dfrac{1}{3}=\dfrac{5}{6}\quad\text{a rational number}$

Solve the system Also plz show work and what you did and these two equations with x and y the x and y have to be the same in bot

Gala2k [10]

Multply both equations by 2 leaving

x + 2y = 8
x - 2y = -2

Add the equations giving

2x = 6
x = 3

Substitute 3 in the top equation

Solve for the variable

krek1111 [17]

Answer:

G = 2/3

Step-by-step explanation:

-13G + 10 = 2(-5G + 4) Distribute the 2 to (-5G + 4)

-13G + 10 = -10G + 8

+13G +13G Add 13G to both sides

10 = 3G + 8

-8 -8 Subtract 8 from both sides

2 = 3G Divide both sides by 3

2/3 = G
