Answer:

7 x = -35

Step-by-step explanation:

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35

- 7 x = 35

7 x = negative 35

7 x = 35

In this problem we need to add the equations below i.e.

11x-3y = -17 and -4x+3y=-18

Adding both equations,

11x-3y+(-4x)+3y = -17+(-18)

7x= -35

or

7 x = negative 35

Hence, the correct option is (c).

Three of these methods gives the correct area of the figure. Which method does NOT?
maw [93]

Ah hah !  NOW I see it.  Thanks to BellBell for a good link.

My first impression is a dog bone standing up on one end.

You're talking about the area of the figure, so I'll think that over
before I look at the choices.

I see:

-- 2 semi-circles = 1 whole circle.
and
-- (1 rectangle) minus (a trapezoid).

Now I'll look through the choices.

A).  No good.  The trapezoid is cut OUT of the figure,
and shouldn't be added into it.

B).  Oh ! Yes !  I didn't look at it that way at first, but
I can see how that works.  'B' is good.

C). and D).  Yes.  This was my description above.

So 'A' is the method that's wrong.

Oksi-84 [34.3K]
First, you need to figure out how many people are paying. Since it is Hank and his two friends, three people will be paying. Next, you need to divide 129.00 by 3. 129/3=43. Each friend will pay exactly $43.00.

Determine side x. Round to the nearest unit. 20 9 12 5
tatyana61 [14]

Answer:

12

Step-by-step explanation:

First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.

Sin 53 degrees = opposite side / hypotenuse side.

The opposite side is x and the hypotenuse side equals 15.

sin53= x/15

15 ( sin 53 ) =x

x= 11.97953

Round

x=12
