What is n in the equation 9n + 2/3 n = 4

1 answer:

3 0

So that they have the same denominator you can rewrite 9n as (27/3)n

(27/3)n + (2/3)n = 4
(29/3)n = 4

Multiply both sides by 3/29 to isolate variable n.

n = 4(3/29)

n = 12/29

Which expressions are equivalent to 4d+6+2d4d+6+2d ? Choose all answers that apply: Choose all answers that apply: (Choice A) A

Sliva [168]

Answer:

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression $4d+6+2d$ and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

$4d+6+2d=(4d+2d)+6$

$4d+6+2d=6d+6$

Let us see which of our given choices matches with our answer.

A. $2(3d+3)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$2*3d+2*3$

$6d+6$

Therefore, option A is a correct choice.

B. $6(d+6)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$6*d+6*6$

$6d+36$

Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.

C. $(3d+3)+(3d+3)$

Upon removing parenthesis we will get,

$3d+3+3d+3$

Upon combining like terms we will get,

$(3d+3d)+(3+3)$

$6d+6$

Therefore, option C is the correct choice.

PLEASE HELP MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE<br> when x=21, y=5. find x when y=25

Anit [1.1K]

This is a simple ratio. x : y. So x = 21 when y = 5.

21 : 5.

x : 25

So you are timesing each side by 5

So 21 x 5 = 105.

x = 105
