Answer:

B

Step-by-step explanation:

Take the three outaide the parentheses and distribute to both terms inside the parentheses. You would then get 3x+15= 15

subtract 15 from the left and right.

3x=0

Which means that x=0/3

So x=0

Interior and Exterior Triangle Angles (0/5)
sweet-ann [11.9K]

Answer:

<h3>      ∠R = 69</h3>

Step-by-step explanation:

<h2>Angle sum property</h2>

Sum of all angles of triangle = 180

     5x - 11 + 3x - 3 + 3x + 18 = 180

      5x + 3x + 3x  -11 - 3 + 18 = 180

Combine like terms

                             11x  + 4 = 180

                                   11x = 180 - 4

                                   11x = 176

                                      x = 176/11

                                       x = 16

∠R = 5x - 11

   = 5*16 - 11

   = 80 - 11

    = 69

90 Points!! PLEASE MAKE SURE THE INORMATION IS CORRECT THAT YOU GIVE ME!
jekas [21]

Answer:

They bought 23 tickets for children and 52 for adults.

Step-by-step explanation:

So first you must find what i represents so here it is

A= Adult

C= Children

They both sold the tickets which is going to be

A + C = 75

Now here it shows

12= each adult ticket

8= each children ticket

find the equation like this 12 A + 8C = 808

Now to find the C

You can find by resolving it like this

C= 75 - A

Solve the A and C

4A = 208

A = 52

12 (52) + 8C = 808

624 + 8C = 808

Children = 23

Adult= 52

14. A bag contains 20 marbles. There are 4 blue
Vladimir [108]

Answer:

30%, or 1/3

Step-by-step explanation:

If there are 20 total marbles, and 6 of them are red, to find the probability of pulling a red marble you would do 6/20, which simplifies to 1/3. This can also be written as 30%.

Hope this helps! :)

Use complete sentences to describe the transformation that maps ABCD onto its image.
Lapatulllka [165]

General Idea:

When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation.

Say a point P(x, y) moves up or down ' k ' units, then we can represent that transformation by adding or subtracting respectively 'k' unit to the y-coordinate of the point P.

In the same way if P(x, y) moves right or left ' h ' units, then we can represent that transformation by adding or subtracting respectively 'h' units to the x-coordinate.

P(x, y) becomes P'(x\pm h, y\pm k). We need to use ' + ' sign for 'up' or 'right' translation and use ' - ' sign for ' down' or 'left' translation.

Applying the concept:

The point A of Pre-image is (0, 0). And the point A' of image after translation is (5, 2). We can notice that all the points from the pre-image moves 'UP' 2 units and 'RIGHT' 5 units.

Conclusion:

The transformation that maps ABCD onto its image is translation given by (x + 5, y + 2),

In other words, we can say ABCD is translated 5 units RIGHT and 2 units UP to get to A'B'C'D'.
