N/2+5=3

move +5 to the other side

sign changes from +5 to -5

N/2+5-5= 3-5

N/2= -2

Mutiply both sides by 2/1

N/2*2/1 - Cross out 2 and 2 , divide by 2 then becomes N

-2(2)/1= -4/1= -4

N= -4

Answer : N= -4

Good evening ,

_______

Answer:

N = -4.

___________________

Step-by-step explanation:

N/2+5=3 ⇔ N/2 = 3 - 5 ⇔ N/2 = -2 ⇔ N = -2 × 2 ⇔ N = -4.

Filomena applies the commutative property to the product. (7/15)⋅(−11)⋅(30) Which expression illustrates the commutative propert
dedylja [7]

  • The commutative property is a number property where the answer obtained is the same no matter the position of the numbers you are multiplying together.

  • Commutative property of multiplication is expressed as:

        a x b = b x a

        a x b x c = a x c x b = b x c x a

  • Note: " . " in the question also means "x" (multiplication)

  • Applying commutative property to the question:

(7/15)⋅(−11)⋅(30)

(7/15) ⋅ (−11) ⋅ (30) = (7/15) . (30) . (11)

The values interchanged are: 11 and 30. The result of the multiplication remains unchanged.

Option A  is the correct answer.

1+sin(a)/1+csc(a)=tan(a)/sec(a)
strojnjashka [21]

Answer:

Below.

Step-by-step explanation:

( 1 + sin a) / (1 + csc a)

= (1 + sin a ) /( 1 + 1/ sin a)

= ( 1 + sin a) /  (sin  a + 1)/  (sin a)

=  (sin a(1 + sin a)) / (1 + sin a)

= sin a.

tan a / sec a

= (sin a / cos a) / (1  /cos a)

= (sin a cos a) / cos a

= sin a

The two expressions are both equal to sin a:

Therefore

(1 + sin a) /( 1 + csc a)  =  tan a / sec a.

Multiple choice can someone please answer please
Furkat [3]

Answer:

n = 6

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

\frac{GH}{QR} = \frac{FH}{PR} , substitute values

\frac{n}{9} = \frac{4}{6} ( cross- multiply )

6n = 36 ( divide both sides by 6 )

n = 6
