Answer:

NaOH(s) --> Na+(aq) + OH–(aq)

Step-by-step explanation:

A basis of Arrhenius is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution.

So the answer is :

NaOH(s) --> Na+(aq) + OH–(aq)

Which expression is equivalent to x2+3x+ 3+ (2x+134+15) - (x+5))

tia_tia [17]

Answer:

$x^{2} + ( 4x) + (147)$

Step-by-step explanation:

Here, the given expression is

$x^{2} +3x +3 + (2x+134+15) - (x+5)$

Now, simplifying the brackets, we get

$x^{2} +3x +3 + (2x+134+15) - (x+5)$ = $x^{2} +3x +3 + 2x+134+15 - x -5$

Now, operate on the like terms.

= $x^{2} + ( 3x + 2x -x) + (134 + 15 + 3 -5)$

= $x^{2} + ( 4x) + (147)$

Hence, the given expression is simplified to the quadratic equation $x^{2} + ( 4x) + (147)$

Solve the equation q+5/9=5/6 q=?

Anna [14]

Answer:

q = 5/18

Step-by-step explanation:

q + 5/9 = 5/6

Subtract 5/9 from each side

q + 5/9 - 5/9 = 5/6 - 5/9

q = 5/6 - 5/9

Get a common denominator of 18

q = 5/6 *3/3 - 5/9 *2/2

q = 15/18 - 10/18

q = 5/18

Help please

Tatiana [17]

Answer:

-2x + 1/2y = 3/2

(x - 3y = 2) ×2

-2x + 1/2y = 3/2

(+) 2x -6y = 4

0 - 11/2y = 11/2

y = -1

substitute y into x - 3y = 2

x = 2 + 3(-1)

x = -1
