Answer:

4 wooden and 3 plastic

Step-by-step explanation:

4 (wooden) × 2 - 5 = 3 plastic

3 (plastic) + 4 (wooden) = 7 total

The number of plastic frames is 4 and the number of wooden frames is 3.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given statement:

The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.

The total number of frames sold by Tristan is 7.

Write the equation for the above statement,

p = 2w - 5

Here, p is a plastic frame and w is a wooden frame,

p + w = 7

Solve the equation by using the elimination method,

p = 4 and w = 3

Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function

The sum of the coordinates of the point is 7.25

The reason the above values are correct is as follows;

The given parameter is;

The point (9, 7) is on the graph y = f(x)

Required:

A point on the graph, 2·y = (f(2·x)/2) + 2

Solution:

Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;

f(2·x) = f(2 × 9/2) = f(9) = 7

Therefore;

2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5

y = 5.5/2 = 2.75

y = 2.75

The coordinate of the point is (x, y) = (2.75, 9/2)

The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Answer:

40 students

Step-by-step explanation:

If the tickets are 1/5 that means they cost 4/5

25 * 4/5 = 20

The tickets cost 20 and the train costs 15 so the total per person is 35

Teachers: 2 at 35 = 70

1500 -70 = 1430

Take 1430 / 35 =40.85714286

We can send 40 students

Answer:

40

Step-by-step explanation:

since the school allots £1500 to spend on a trip to the theatre.  Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off

therefore 4/5*35 = 28 for the tickets

:

A train ticket for the day will cost £15 each.

therefore total cost for each: 28 + 15 = 43 pounds each

:

If 2 teachers and the maximum number of students attend, how much money will the school have left over?

:

let s = no. of students

43(s+2) =< 1500

43s + 86 =< 1500

43s =< 1500 - 86

43s =< 1414

s =< 1414/43

s =< 32.88, 32 students max

:

find how much left over. plus 2 teachers = 34 people

1500 - 43(34) =

1500 - 1462 = 38 pounds left over

x = -11

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11
