The correct answer is 3.5

Two chords AC and BD are intersecting inside the circle. The Intersecting Chord Theorem states that when two chords intersect inside a circle, the products of their segments are equal.

Thus, for the given circle:
(AE) × (EC) = (BE) × (ED)

The lengths of the segments are
AE = 7
EC = 2
BE = 4
ED = ?

To solve for ED, we simply substitute the known values into the equation
ED =  \frac{7(2)}{4} = \frac{14}{4} = 3.5

Solve the system using elimination,<br> 2x - 3y = - 19<br> 7x + 7y = 21
blagie [28]

Answer:

x = -2

y = 5

Step-by-step explanation:

2x - 3y = -19  ---------------------------(I)

7x+ 7y = 21  -----------------------------(II)

Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x

(I)*7              14x - 21y = - 133

(II)* 3           <u> 21x + 21y = 63  </u>        {Now add}

                   35x          = -70

                                x = -70/35

x = - 2

Plug in x = - 2 in equation (I)

2*(-2) - 3y = -19

-4 -  3y  = -19

     -3y = -19 + 4

     -3y = -15

         y = -15/-3

y = 5

Jace is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Jace will earn $50
riadik2000 [5.3K]

Answer:

The number of commercials is 340 and the number of movies are 334.

Step-by-step explanation:

Let the number of commercials be = C

    number of movies be = M

According to given conditions:

C = 6 + M    --------- eq1

C + M + 6 = $680 ------ eq2

Putting eq1 in eq2:

6 + M + 6 + M = $680

12 + 2M = $680

Subtracting 12 from both sides:

2M = $680 - 12

2M = 668

Dividing both sides by 2:

M = 668/2

M = 334

For finding number of movies put value of M in eq 1

C = 334 + 6

C = 340

So The number of commercials is 340 and the number of movies are 334.

i hope it will help you!

After increasing by 30% it became $520?
Alex
So from 100% you increased it by 30% to become 520
130%=540
percent means parts out of 100
130%=130/100=1.3
1.3 of whole=520
divide both sides by 1.3
whole=400

the number was 400
