Step-by-step explanation:

(1)

1 x = 12

3

multiply both sides by the 3

3 × 1 x = 12 × 3

3

x = 36

(2)

3x + 3 = 21

( group like terms)

3x = 21 - 3

3x = 18

( divide both sides by 3)

3x = 18

3 3

x = 6

(3)

9.95 + 0.30( 35 )

=9.95 + 10.5

=20.45

(4)

(4)

(I'm not soo sure about this one)

equation = 6x + 27 = x

11

solution

( multiply both sides by 11)

= (6x + 27) ×11 = x × 11

11

= 6x + 27 = 11x

( grouping like term)

27 = 11x - 6x

27 = 5x

(divide both sides by 5)

27 = 5x

5 5

x = 5.4

the number of shirt they can buy is 5 or 5.4

Which equation has the solutions X=1 +-SQRT 5?
Vesna [10]

Answer:

D is correct. x^2-2x-4=0

Step-by-step explanation:

We are given the root of the equation

x=1+\pm \sqrt{5}

If we are given solution of the equation then find equation using formula.

If a and b are the solution of equation then equation would be (x-a)(x-b)=0

Here, a=1+\sqrt{5} , b=1-\sqrt{5}

Equation form would be (x-1-\sqrt{5})(x-1+\sqrt{5})=0

Now we simplify the above equation to get correct option.

x^2-x+x\sqrt{5}-x+1-\sqrt{5}-x\sqrt{5}+\sqrt{5}-5=0

x^2-2x-4=0

So, D is correct.  x^2-2x-4=0
