Does anyone know what math topic this is?

Step-by-step explanation:

breadth=x

length is 5m long then breadth

length=x+5

Perimeter=2(length+breadth)

subtitute values in formula:

150=2(x+5+x)

2x+5=150/2

2x+5=75

2x=75-5

2x=70

x=70/2

x=35

breadth=35m

length= x+5

length=35+5

length=40m

[tex] \text{Let us assume the breadth be } \purple{\frak{a}}[/tex]

The length is 5m more than its breadth

[tex] \text{The length be} \: \green{\frak{a + 5}}[/tex]

Here we need to get both breadth and length by finding out a

[tex] \hookrightarrow \frak{{ \sf P}erimeter_{(Rectangle)} =2 (Length + Breadth)} \\ \\ \hookrightarrow \frak{150 =2 (a + 5 + a)} \\ \\ \hookrightarrow \frak{150=2 (2a + 5)} \\ \\ \hookrightarrow \frak{150=4a + 10} \\ \\ \hookrightarrow \frak{4a = 150 - 10} \\ \\ \hookrightarrow \frak{4a = 140} \\ \\ \hookrightarrow \frak{a = \cancel \frac{140}{4} } \\ \\ \star \quad \underline{\boxed{\frak{ \blue{a = 35}}}}[/tex]

[tex] \bigstar \underline{ \frak{Finding \: them}} : [/tex]

[tex] \qquad\odot \: \: \frak{Length = a + 5 = 35 + 5 = \pink{40m}} \\ \\

\qquad\odot \: \: \frak{Breadth = a= \pink{35m}}[/tex]

[tex]\\ \sf\longmapsto -7\dfrac{8}{45}[/tex]

[tex]\\ \sf\longmapsto \dfrac{45(-7)+8}{45}[/tex]

[tex]\\ \sf\longmapsto \dfrac{315+8}{45}[/tex]

[tex]\\ \sf\longmapsto \dfrac{323}{45}[/tex]

[tex]\\ \sf\longmapsto 7.1[/tex]

Step-by-step explanation:

1. Let the number be a

2 + 3a = (-10)

3a = -10 - 2

3a = -12

a = -12/3 = -4.

2. Let the number be x

3x + 20 = 11

3a = 11 - 20

3a = -9

a = -9/3 = -3

3. Let the number be n

7x/10 = 5.6

x = 5.6 × 10/7

x = 56/7

x = 8

Answer:

No

Step-by-step explanation:

It would be x(5*2)

Basically what you put just written correctly

Answer:

yes it is 10x

Step-by-step explanation:

you just simply multiply 5 and 2 to get 10 and keep the x and put it next to the 10. Therefore, (5•2) x = 10x

Answer:

30%

Step-by-step explanation:

Answer:

Both numbers = 27

Step-by-step explanation:

( x + x + 49 + 25 + 42)/ 5 = 34          Multiply both sides by 5

(2x + 49 + 25 + 42) = 34*5 = 170     Combine the left

(2x + 116) = 170                                 Remove the brackets.

2x + 116 = 170                                   Subtract 116 from both sides

2x = 170 - 116

2x = 54                                             Divide by 2

x = 54/2

x = 27

Check

27 + 27 + 49 + 25 + 42

170 / 5 = 34

It does check out.

27 is right.

Option A "4, 6, 8".

This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.

Therefore, Option A is the correct answer.

Thank You...

Answer:

6285 rounded to nearest hundred would be 6300.

6000 isn't right because you are rounding it to nearest thousand i.e. 6000.

Hope you get this

Answer:

No. It would be 6,300.

Step-by-step explanation:

To the nearest thousand, it would be 6,000.

To the nearest hundred, it would be 6,300.

To the nearest ten, it would be 6,290.

Answer:

A

Step-by-step explanation:

Note that the dots in both the upper and lower row increase by 1

The 3rd diagram has 4 dots in the upper and 3 in the lower , then

the next diagram should have 5 dots in the upper and 4 in the lower

This is the case in diagram A

Answer:

A

Step-by-step explanation:

I'm assuming p is an exponent.

You can multiply the exponent p with 9

8^9p = 8^18

Now we know that some number times the exponent 9 gives us 18.

Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)

therefore, 9p=18

p=18/9

p=2

Answer:

Step-by-step explanation:

Unless you know that the top angle is a right angle (an assumption you should never make, but I will do it here because there is no other way to do it.)

Find the missing side of the triangle that is on the bottom triangle

b^2 = c^2 - a^2

b = ?

c = 11

a = 10

b^2 = 11^2 - 10^2

b^2 = 121 - 100

b = sqrt(21)

Now using the fact that

b / 10 = 10 / (x - b)          

We know b from the previous problem

b = sqrt(21)

So now cross multiply

b ( x - sqrt(21) ) = 100

sqrt(21) * x - 21 = 100         Add 21 to both sides.

sqrt(21)x = 121                   Divide by sqrt(21)

x = 121/sqrt(21)

x = 26.4

My first inclination is to tell your teacher it is unsolvable. Or you can ask him or her to show you how it is done.  If they think the assumption I have made is correct, then you have the answer. Technically however, there is no answer.
