Answer:

D.

Step-by-step explanation:

In triangle EAK, A is the right angle.

In triangle AGK, G is the right angle.

In triangle EGA, G is the right angle.

That means we know that those letters have to be in the same position in the names of the three triangle.

The triangles are being written in the order: EAK, AGK, EGA

_A_   ~   _G_   ~   _G_

Angle E of triangle EAK corresponds to angle E of triangle EGA.

EA_   ~   _G_   ~   EG_

Angle K of triangle EAK corresponds to angle K of triangle AGK.

EAK   ~   _GK   ~   EG_

There is only one vertex missing in the last two triangles, so they must be A and A.

EAK   ~   AGK   ~   EGA

Answer: D.

So we know that the difference is 235.

And a red and green put together is 92 balloons * 5.
So 5 red and green balloons put together is 460, or 92*5.

460-235=225

225/9=25

92-25=67

So 5*67 and 4*25 is 435.

Your final answer should be 435 balloons in total.

Answer:

Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

Step-by-step explanation:

Let us represent:

Number of tickets sold on Tuesday = a

Number of tickets sold on Wednesday = b

Number of tickets sold on Thursday = c

In three days Alexandra sold a total of 31 tickets to her school play.

a + b + c = 31...... Equation 1

On Tuesday she sold as twice as many tickets as on Wednesday.

2a = b

And on Thursday, she sold exactly seven tickets.

c = 7

Substitute 2a for b and 7 for c in Equation 1

a + b + c = 31...... Equation 1

a + 2a + 7 = 31

3a = 31 - 7

3a = 24

a = 24/3

a = 8 tickets

Note that

2a = b

a = 8 tickets

2 × 8 = 16 tickets

b = 16 tickets

Therefore, Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

Answer:

40

Step-by-step explanation:

First, we must know that ab is the same as:

a × b

Now, since a is given as 8, we can substitute a with 8. This is shown below:

ab = 8 × b

Similarly, b is given as 5. So, we can substitute b with 5:

ab = 8 × 5

With this, we can now evaluate ab as shown below:

ab = 8 × 5

= 40

Answer:

6 rows

Step-by-step explanation:

You divide 18 by 3 and you have ur answer.

Answer:

6 flowers per row

Step-by-step explanation:

Divide the number of flowers by the number of rows:

⇒ 18 ÷ 3 = 6

So she will plant 6 flowers per row.

Answer:

Obtuse scalene triangle

Answer:

So cool

Hahahah

Step-by-step explanation:

Let's set up the variables for the two numbers --> 'a' , 'b'

Now let's set up some equations based on the given information:

Equations:

   Solve (equation 1) for b in terms of a

     b = a - 6 -- equation 3

    (equation 3) into (equation 2)

     a^2 + (a - 6)^2 = 90

     a^2 + a^2 - 12a + 36 = 90

     2a^2 - 12a - 54 = 0

     (2a + 6)(a - 9) = 0

       a = -3 -- equation 4

       a = 9 -- equation 5

    (equation 4) into (equation 1)

      -3 + b = 6

       b = 9  - ---   a = -3, b= 9

    (equation 5) into ( equation 1)

     9 + b = 6

     b = -3 - ---     a = 9, b= -3

Since the numbers are interchangeable, the two numbers are -3 and 9.

Answer:

Step-by-step explanation:

Let number be "n".

Half a number added to the number = 240

This means

0.5n + n = 240

1.5n = 240

Divide both sides by 1.5

n = 240/1.5 = 160

Quotient = 13

Remainder = 0

Step-by-step explanation:

Quotient = 13

Remainder = 0

Answer:it’s 13

Step-by-step explanation:49+94/11=13

Answer:

D: 2.67

Step-by-step explanation:

Assuming that both vertical lines are parallel, there are rules regarding angle sizes.

The rule that is specific to this question is alternate angles, this is when two angles are of the same size when they are on opposite sides of the line. This means that both equations equal each other:

10x + 13 = -3 + 16x

Add 3 to both sides to remove the negative 3 and isolate the 16x:

10x + 13 + 3 = 16x

10x + 16 = 16x

Subtract 10x from both sides of the equation to simplify:

10x + 16 - 10x = 16x - 10x

16 = 6x

Divide both sides by 6 to simplify:

6x = 16

[tex]x = \frac{16}{6}\\x = \frac{8}{3}[/tex]

Or in decimal form,

[tex]2.\overline{6} \\= 2.67[/tex]

Answer:

x = 13 , x = 9

Step-by-step explanation:

for the lines to be parallel then 9x + 2 and 119 are alternate angles and are congruent , so

9x + 2 = 119 ( subtract 2 from both sides )

9x = 117 ( divide both sides by 9 )

x = 13

-------------------------------------------------------

For f and g to be parallel then 18x - 44 and 8x - 10 are same- side interior angles and sum to 180° , then

18x - 44 + 8x - 10 = 180 , that is

26x - 54 = 180 ( add 54 to both sides )

26x = 234 ( divide both sides by 26 )

x = 9

Answer:

(x+5)(x+25)=5

Step-by-step explanation:

When simplified, if you foil the left side of the equation, you get:

x^2+30x+125 = 5

Simplified, you get:

x^2+30x+120 = 0

A quadratic by definition is a polynomial with the highest degree of 2, which means the highest exponent should be a two. In our case, it is. So therefore, (x+5)(x+25)=5 is the answer.

Answer:

Option 1

Step-by-step explanation:

(x + 5)(x + 25) = 5 is a quadratic equation. It can be verified upon expansion.

=> x² + 30x + 125 = 0

=> Quadratic equations are of the form Ax² + Bx + C = 0

=> Hence it is a quadratic equation
