Answer:

  -2

Step-by-step explanation:

Between the first two steps we see ...

  15(x-\boxed{^})=25\\\\15x+30=25

Applying the distributive property to the first equation and comparing to the second, we see that ...

  -15\boxed{^}=30\\\\\boxed{^}=\dfrac{30}{-15}=-2

The number in the box should be -2.

Step-by-step explanation:

In figure:

∠PRT+∠RTP+∠TPR=180

O

(angle sum property of triangle)

⇒x+(180

O

−∠RTQ)+60

O

=180

O

(linear pair)

⇒x+(180

O

−97

0

)+60

o

=180

O

⇒x=31

o

Now, ∠PRT+∠TRQ+∠QRS=180

O

(angle of straight line)

⇒x+48

o

+y=180

O

⇒31

At a regional soccer​ tournament, tickets for two adults and seven students cost ​$60. Tickets for three adults and eleven stude
den301095 [7]

Answer:

The price of an adult ticket is $9 and the price of a student ticket is $6

Step-by-step explanation:

Create a system of equations where x is the price of an adult ticket and y is the price of a student ticket:

2x + 7y = 60

3x + 11y = 93

Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2, to cancel out the x terms:

6x + 21y = 180

-6x - 22y = -186

Add them together:

-y = -6

y = 6

Then, plug in 6 as y into one of the equations to solve for x:

2x + 7y = 60

2x + 7(6) = 60

2x + 42 = 60

2x = 18

x = 9

So, the price of an adult ticket is $9 and the price of a student ticket is $6

ASAP! Simplify -5 - square root -44
Tju [1.3M]

Answer:

\boldmath-5-2i\sqrt{\boldmath11}

Step-by-step explanation:

The not simplified form is -5-\sqrt{-44}

you know that \sqrt{a\times b} = \sqrt{a} \times\sqrt{b} is true a and b are both positive or one of it is negative (not both of them).

You can write -44 as -1 × 4 × 11 inside square root.

So, \sqrt{-44} = \sqrt{-1\times4\times11}=\sqrt{-1}\times\sqrt{4}\times\sqrt{11}=i\times2\times\sqrt{11}         (\sqrt{4}=2)

\therefore -5-\sqrt{-44} = -5-2i\sqrt{11}

(NOTE : You must know that \boldmath\sqrt{\boldmath-1} is written as \boldsymbol i )
