Answer:

Brass + Brass = Woodwind

Brass + Woodwind = 150

Brass = 50, Woodwind = 100

Step-by-step explanation:

Hi there!

The two addition equations would be:

Brass + Brass = Woodwind

(As there are twice as many woodwind as brass)

AND

Brass + Woodwind = 150

(As there are 150 of those instruments in total)

These two equations fully describe this situation, and you can use them to solve the problem using substitution as well.

Since Woodwind = Brass + Brass, then:

Brass + Woodwind =150

Can also be written as:

Brass + (Brass+Brass) = 150

Now we can solve by combining all the like terms which gives us:

3*Brass = 150

Brass = 150/3

Brass = 50 meaning that Woodwind = 100, as 50+50=100.

Hope this helped!

Answer:

Step-by-step explanation:

Equation in which to find the slope:

(slope) [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (9 , -4)\\(x_2 , y_2) = (9 , 5)[/tex]

Plug in the corresponding numbers to the corresponding variables:

[tex]m = \frac{5 - (-4)}{9 - 9}[/tex]

Simplify. First solve the numerator and denominators, then divide:

[tex]m = \frac{5 - (-4)}{ 9 - 9} \\m = \frac{5 + 4}{9 - 9} \\m = \frac{9}{0}[/tex]

Because a fraction cannot be out of 0, your answer will be .

Answer:

C(t) = 25+34.37t

Step-by-step explanation:

It is given that,

The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.

We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.

At t=0, Jonathan pays $25 as joining fee.

Equation will be :

C(t) = Co+kt

Initially, Co = 25

C(t) = 25

At t = 8,

C(8) = 25 + k(8) = 300

8k = 275

k = 34.37

⇒ C(t) = 25+34.37t

Hence, this is the required equation.

Answer:

5

Step-by-step explanation:

5 courses worth 4 credits have Diego completed. Therefore, option B is the correct answer.

We need to find how many courses worth 4 credits has Diego completed.

In mathematics, a system of equations, also known as a set of simultaneous or an equation system, is a finite set of equations for which we sought common solutions. A system of equations can be classified in a similar manner as single equations.

Now, let the courses worth 3 credits be x and the courses worth 4 credits be y.

Now, in total Diego completed 18 courses

That is, x+y=18 ------(I)

Diego has earned a total of 59 credits

So, 3x+4y=59 ------(II)

Multiply the equation (I) by 3, that is 3x+3y=54 ------(III)

Now, subtract the equation (III) from (II) and simplify.

That is, 3x+4y-(3x+3y)=59-54

⇒y=5

Substitute y=5 in the equation (I) and simplify

That is, x=13

Therefore, 5 courses worth 4 credits have Diego completed.

Answer:

16 ft²

Step-by-step explanation:

The complete question is attached.

A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.

The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.

Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:

The area of a trapezoid = [(3 + 5)/2] * 4

The area of a trapezoid = 16 ft²

Answer:

The area of the rectangle VWXY is 52 square units

Step-by-step explanation:

The formula of the area of the rectangle is A = L × W, where

From the given figure

∵ VWXY is a rectangle

∵ V = (3, -9) and W = (-1, -9)

∵ X = (-1, 4) and Y = (3, 4)

∵ Its length is WX or VY

∴ WX = VY

∵ Its width is VW or XY

∴ VW = XY

→ Let us find its length and its width

∵ Points W and X have the same x-coordinates

∴ y1 = -9 and y2 = 4

→ By using the 4th note above

∴ WX = 4 - -9 = 4 + 9 = 13  

∴ L = 13 units

∵ Points X and Y have the same y-coordinates

∴ x1 = -1 and x2 = 3

→ By using the 3rd note above

∴ XY = 3 - -1 = 3 + 1 = 4  

∴ W = 4 units

→ By using the formula of the area above

∵ A = 13 × 4

∴ A = 52 square units

∴ The area of the rectangle VWXY is 52 square units

Answer:

A = 112 square feet

Step-by-step explanation:

The perimeter of a rectangular garden is 46 feet.

P = 2(l+b)

46=2(l+b)

23 = (l+b) ....(1)

Let length is l and breadth is b.

The length of the garden is 5 feet less than three times the width.

l = 3b-5 ...(2)

Put equation (2) in equation (1)

23 = (3b-5+b)

23 = 4b - 5

28 = 4b

b = 7 feet

Pu b = 7 in equation (2)

l = 3(7)-5

l = 16feet

Area of a rectangle is given by :

A = lb

A = 16 × 7

= 112 ft²

So, the area of the garden is 112 square feet.
