well #7 is a solution.

y= 9x (4,36)

9 times 4 = 36

36/9=4

so the ordered pair is a solution.

y=3x-5 (7,16)

3 times 7 -5= 16

so once again the ordered pair is a solution.


Hoped this helped.

On one of the day you went to the gym, the ratio of men to women was 3 : 2.
balu736 [363]

Answer

Find out the  how many women were there .

To prove

Let us assume that the x is the scalar multiple of men and women.

As given

The ratio of men to women was 3 : 2.

Than

The total number of men = 3x

The total number of women = 2x

As given

If 120 men used the gym.

thus

120 = 3x

x = \frac{120}{3}

x = 40

The total number of women = 2 × 40

                                               = 80

Therefore 80 women were there in the gym .

2(2x + 3) = -6(x + 9)
sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6  

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.
