Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )

Answer:

(4, -11)

Step-by-step explanation:

We are given the system of equations:

[tex]\displaystyle \begin{cases} 3x+2y=-10\\ y=-5x+9\end{cases}[/tex]

And we want to solve by substitution.

Notice that y is isolated in the second equation.

Therefore, we can substitute the second equation into the first. This gives us:

[tex]3x+2(-5x+9)=-10[/tex]

Now, we can solve for x.

First, distribute:

[tex]\displaystyle 3x-10x+18=-10[/tex]

Next, we can combine like terms:

[tex]-7x+18=-10[/tex]

Subtract 18 from both sides:

[tex]-7x=-28[/tex]

And divide both sides by -7:

[tex]x=4[/tex]

So, the value of x is 4.

Using the second equation then, we can solve for y:

[tex]y=-5x+9[/tex]

Since we know that x = 4:

[tex]\displaystyle y = - 5(4) + 9 = -20 + 9 = -11[/tex]

So, our solution is (4, -11).

To check, we can simply substitute the x and y values and see if the two equations are true.

For the first equation:

[tex]3(4)+2(-11)=12-22=-10\stackrel{\checkmark}{=}-10[/tex]

And for the second equation:

[tex]-5(4)+9=-20+9=-11\stackrel{\checkmark}{=}-11[/tex]

Since both statements are true, (4, -11) is indeed correct!

Answer:The difference between the number of children and adults=153

Step-by-step explanation:

ratio of men to women to children is 1:3:20

Total RATIO = 1+ 3+ 20= 24

Number of men = ratio of men / Total ratio x  Total Number of people on the trip =

= 1/24 x 216= 9 men

Number of women=ratio of women / Total ratio x  Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women

Number of children=ratio of Children/ Total ratio x  Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children

The difference between the number of children and adults will be 180 -27 = 153

Answer:

C =-x + 550

Step-by-step explanation:

Complete question

At $350 per person, an airline anticipates selling 200 tickets for a particular flight. At $450 per person the airline anticipates selling 100 tickets for the same flight .Find the linear equation between the cost per ticket and the number of tickets.

Find the complete question attached

Let x be the total number of tickets sold

C be the cost per ticket

If C = $350, x = 200

when C = $450, x = 100

Get the slope

m = C2-C1/x2-x1

m = 450-350/100-200

m = 100/-100

m = -1

Substituting into the point slope form of the equation;

C - C1 = m(x-x1)

Substituting m = -1, C1 = 350 and x1 = 200

C - 350 = -1(x-200)

C - 350 = -x + 200

C = -x + 200 + 350

C = -x + 550

Hence the required linear equation is C =-x + 550

The linear equation should be C =-x + 550

Here we assume x be the total number of tickets sold

And,

C be the cost per ticket

Since C = $350, x = 200 and C = $450, x = 100

So, here the slope should be

[tex]m = C2-C1\div x2-x1\\\\m = 450-350\div 100-200\\\\m = 100\div -100[/tex]

m = -1

Now here we Substituting into the point slope form

So,

C - C1 = m(x-x1)

Here m = -1, C1 = 350 and x1 = 200

Now

C - 350 = -1(x-200)

C - 350 = -x + 200

C = -x + 200 + 350

C = -x + 550

Answer:

Step-by-step explanation:

Probably anyway

Answer:

Step-by-step explanation:

given tanB= 4/3

so sinB=4/5

n cosB=3/5

given BC=15

BA=BC*cosB

=15*3/5

=9

AC=BC*sinA

=15*4/5

=12

Triangle ABC and DBE are similar by AAA

DB= BA-AD

=9-3

=6

DB/BA=DE/AC

6/9=DE/12

DE=12*6/9

=8

Answer:

DE = 8

Step-by-step explanation:

ΔABC and ΔDBE are similar.

As they share the same angles, the sides are in proportion to each other.

Therefore, we can solve using ratios.

Tan trigonometric ratio

[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]

where:

Given:

  [tex]\sf \tan (B)=\dfrac{4}{3}[/tex]

Therefore:

[tex]\implies \sf \dfrac{DE}{BD}=\dfrac{AC}{BA}=\dfrac{4x}{3x}[/tex]

We know that BC = 15 and that AC : BA = 4x : 3x

Using Pythagoras' Theorem:

[tex]\implies \sf (3x)^2+(4x)^2=15^2[/tex]

[tex]\implies \sf 9x^2+16x^2=225[/tex]

[tex]\implies \sf x^2(9+16)=225[/tex]

[tex]\implies \sf x^2=9[/tex]

[tex]\implies \sf x=3[/tex]

Therefore,

⇒ AC = 4 · 3 = 12

⇒ BA = 3 · 3 = 9

Now we have found the length of BA, we can find the length of BD:

⇒ BD = BA - DA

⇒ BD = 9 - 3

⇒ BD = 6

As DE : BD = 4x : 3x  and  BD = 6 then:

⇒ 3x = 6

⇒ x = 2

Therefore, to find DE, substitute x = 2:

⇒ DE = 4x

⇒ DE = 4(2)

⇒ DE = 8
