Answer:

(-7/2, -5/2).

Step-by-step explanation:

[(-5 + (-2))/2),  (-3 + (-2))/2)]

= (-7/2, -5/2).

Answer:

here you go :)

Step-by-step explanation:

You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).

If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at:  3 + 4 = 7

The x coordinate of the STARTING point would have been 7.

You can do the same with the y-coordinate: start at 4 and travel down 1 unit.  The y-coordinate of the STARTING point would be 3.

Therefore, the coordinates of the starting point would have been  (7,3)

Answer:

let length of Ribbon B l

Therefore

L=30

Ribbons cutted in ratio 5 is to 3

Therefore length of ribbonS

Be 30*5

=150

And 3*30=90

Therefore lengths of ribbons be 150 and 90

hope this helps :)

have a great day ahead!

Answer:

38

Step-by-step explanation:

(4x-8)+36 = 180

4x - 8+36 = 180

4x +28 = 180

4x = 180-28

4x = 152

x = 152/4

x = 38

Answer:  31.5 square units

Explanation:

The area of the rectangle is length*width = 7*3 = 21 square units

The area of the triangle is 0.5*base*height = 0.5*7*3 = 10.5 square units

The combined area is 21+10.5 = 31.5 square units

Answer:

The student may have forgotten the negative signs.

Step-by-step explanation:

Obviously, 4+5 = 9. However, this student may have forgotten that negative plus negative is equal to further negative, which is what we want. Instead, the answer 5 was provided, which leads to an incorrect sum of 1.

Answer:

(-6, -2)

Step-by-step explanation:

[tex]f(x) = {x}^{2} + 12x + 34[/tex]

[tex] = f(x) = {1x}^{2} + 12x + 34[/tex]

= a = 1, b = 12

[tex] = x = - \frac{12}{2 \times 1} [/tex]

[tex] = x = - \frac{12}{2} [/tex]

= x = -6

[tex] = f(x) = {x}^{2} + 12x + 34.. = - 6[/tex]

[tex] = f( - 6) = - 2[/tex]

= (-6, -2)

Step-by-step explanation:

Total sales

Rs 5000- Rs 500= Rs 4500

The required amount received by the businessmen is 4500, from the sale.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the money businessman get be x,
According to the question,
x + commission of the agent = 5000

x + 500 = 5000
x = 4500

Thus, the required amount received by the businessmen is 4500.

Answer: 480

Step-by-step explanation:

The quadrilateral ABCD is a trapezium

The formula for area of trapezium is

Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h

So we can place the given values into the formula.

We get

Area = 1/2 × (9+15) × 40

Area = 1/2 × 24 × 40

By multiplying all of them we get

Area = 480cm

Answer:

[tex] \frac{271}{100} [/tex]

Step-by-step explanation:

hopefully it makes sense

:)

The decimal 2.71 can be written as the simplified fraction as 271/100.

Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.

Here p, called the numerator and q, called the denominator, are real numbers.

The given number is 2.71.

We can write 2.71 as 2.71 / 1, since any number divided by 1 is the number itself.

Multiplying both numerator and denominator of 2.71 / 1 with 100, we get,

(2.71 × 100) / (1 × 100)

= 271/100

This cannot be simplified further since 271 is a prime number.

Hence the simplified fractional form of 2.71 is 271/100.

Answer:

[tex]3[/tex]

Step-by-step explanation:

[tex] - 3( - 5x + 2) + x - 3 = 39[/tex]

[tex]15x-6+x-3 = 39[/tex]

[tex] 16x-9= 39[/tex]

[tex] 16x= 39+9[/tex]

[tex] 16x=48[/tex]

[tex]x = 48-16[/tex]

[tex]x = 3[/tex]

Answer:

x = 3

Step-by-step explanation:

Given

- 3(- 5x + 2) + x - 3 = 39 ← distribute parenthesis and simplify left side

15x - 6 + x - 3 = 39

16x - 9 = 39 ( add 9 to both sides )

16x = 48 ( divide both sides by 16 )

x = 3

Answer:

15.

Step-by-step explanation:

3(x - 14) = 3

3x - 42 = 3

3x = 42 + 3 = 45

x = 15.

Let the number = x

Set up the equation:

3(x-14) = 3

Simplify:

3x -42 = 3

Add 42 to both sides

3x = 45

Divide both sides by3

X = 15
