Step-by-step explanation:

Answer:

5x - 4 = 11

1/2x + 15 = 9

Step-by-step explanation:

I dont exactly know how u would show work.

If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.

If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.

Answer:

The cost for adult tickets be represented by x = $5

The cost for student tickets be y = $2

Step-by-step explanation:

Let the cost for adult tickets be represented by x

the cost for student tickets be y

The Montague family and their neighbors the Capulets attended the school play together. The Montagues bought two adult tickets and three student tickets for $16.

= 2x + 3y = 16... Equation 1

The Capulets purchased three adult tickets and two student tickets for $19.

3x + 2y = 19 ..... Equation 2

How much was each adult and student ticket?

2x + 3y = 16... Equation 1

3x + 2y = 19 ..... Equation 2

We solve using Elimination method

Multiply Equation 1 by 2 and Equation 2 by 3 to eliminate u

4x + 6y = 32..... Equation 3

9x + 6y = 57.... Equation 4

Subtract Equation 4 from 3

-5x = -25

x = 25/5

x = $5

2x + 3y = 16... Equation 1

Since x = $5

2($5) + 3y = 16

10 + 3y = 16

3y = 16 - 10

3y = 6

y = 6/3

y = $2

Therefore:

The cost for adult tickets be represented by x = $5

The cost for student tickets be y = $2

Answer:

Section A = 26,500 seats

Section B = 14,900 seats

Section C = 11,600 seats

Step-by-step explanation:

Total seats = 53,000

Total revenue = 1,997,400

Section A seat = $42

Section B seat = $36

Section C seat = $30

The number of seats in this in section A equals the total number of seats in section BNC

A = B + C

A + B + C = 53,000 (1)

42A + 36B + 30C = 1,997,400 (2)

Substitute A = B + C into (1)

A + B + C = 53,000

B + C + B + C = 53,000

2B + 2C = 53,000

2(B + C ) = 53,000

B + C = 53,000 / 2

= 26,500

B + C = 26,500 (3)

Substitute B + C = 26,500 into (2)

42A + 36B + 30C = 1,997,400

Recall,

A = B + C

42( 26,500) + 36B + 30C = 1,997,400

1,113,000 + 36B + 30C = 1,997,400

36B + 30C = 1,997,400 - 1,113,000

36B + 30C = 884,400. (4)

Multiply (3) by 30

B + C = 26,500 × 30

30B + 30C = 795,000 (5)

36B + 30C = 884,400 (4)

Subtract (5) from (4) to eliminate C

36B - 30B = 884,400 - 795,000

6B = 89,400

B = 89,400/6

= 14,900

B = 14,900

From (3)

B + C = 26,500

C = 26,500 - B

= 26,500 - 14,900

= 11,600

A = B + C

= 14,900 + 11,600

= 26,500

Section A = 26,500 seats

Section B = 14,900 seats

Section C = 11,600 seats

Answer:

you multiply all of those answers

Step-by-step explanation:

the two shapes are similar but scaled differently

this ratio is 2:3 (EF:AB)

so to find y we’ll set this up

2/3= y/4.5

and solve for y

4.5(2/3) = y

y = 9/3

y = 3

Answer:

p(-2) = -11

p(0) = -3

p(5) = 17

Step-by-step explanation:

Think of p(x) as a y.  Just substitute the x values into the equation, and with some basic algebra, you should get your answer

p(-2) = -3 + (-8) = -11

p(0) = -3 + 0 = -3

p(5) = -3 + 20 = 17

Step-by-step explanation:

The approximate stopping distance d(in feet) is given by the formula :

[tex]d=0.05v^2+2.2v[/tex] ...(1)

Where

v is the speed of the car in mph

We need to find the speed of the car when the distance is 200 feet

Put d = 200 in equation (1)

[tex]0.05v^2+2.2v=200\\\\0.05v^2+2.2v-200=0[/tex]

It is a quadratic equation. Divide the above equation by 0.05.

[tex]v^2+44v-4000=0[/tex]

The solution of the above equation is given by :

[tex]v=\dfrac{-44\pm \sqrt{44^2- 4(1)(-4000)} }{2(1)}\\\\v=\dfrac{-44+ \sqrt{44^2- 4(1)(-4000)} }{2(1)},\dfrac{-44- \sqrt{44^2- 4(1)(-4000)} }{2(1)}\\\\v=44.96\ ft/h, -88.96\ ft/h[/tex]

Since, 1 mph = 5280 ft/hour

44.96 ft/h = 0.00851 mph

-88.96 = -0.0168 mph

Hence, this is the required siolution.

Answer:

The other sides are called legs.

Step-by-step explanation:

Right Triangles

They are a special type of triangles on which one of its internal angles is 90°. Since the sum of all internal angles is 180°, the sum of the other acute angles is 90°.

The longest side is called the hypotenuse and the other two sides are called legs.

The attached image shows a right triangle of hypotenuse c and legs a and b.

Answer:

ΔABC has: AD=DB

                  AE = EC

=> DE is the median line of ΔABC

=> DE // BC

=> m∠AED = m∠ECF = 32°

.

Step-by-step explanation:

Answer:

∠ ECF = 32°

Step-by-step explanation:

DE is the midsegment of Δ ABC and is therefore parallel to the third side BC.

Since DE and BC are parallel lines, then

∠ ECF and ∠ AED are congruent ( corresponding angles ) , thus

∠ ECF = ∠ AED = 32°

Answer:

Point A

Step-by-step explanation:

The long that would be used to find f(3) is the point that shows the value of y when x = 3.

Looking at the graph given, the only point that shows the value of y when x = 3 is point A.

When x = 3, y = 0.

Therefore, f(3) = 0.

Answer:

y is correct but x is not

Step-by-step explanation:

because x+ 118°=180°[ co- interior angle ]

Answer:

98

Step-by-step explanation:

Mathematically, when we add all the angles of a triangle, we get 180

Thus;

x + 1 + 2x-2+ 3x-5 = 180

6x-6 = 180

6x = 186

x = 186/6

x = 31

so the measure of the biggest angle is 3x -5

= 3(31) + 5 = 93 + 5 = 98
