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:

We know that

Area of rectangle = lb

Area = 10(20)

Area = 200 m²

Shaded region = πr²

=> 2 × 22/7 × (10/2)²

=> 2 × 22/7 × 10/4

=> 157 m²

Probability = 157/200 = 78.5%

5.

Area of the biggest circle = πr²

= 22/7 × (20)²

= 1256.6

Area of shaded region

π(10² - 5²)

π(100 - 25)

3.14(75)

235.6

Probability = 235.6/1256.6 = 18.7%

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]2x - 9 = 5x + 12 \\ - 3x = 21 \\ x = - 7[/tex]

Step-by-step explanation:

x = -7

Step-by-step explanation:

[tex]here \: given \: that \: total \: lenth = bd = 67 \\ then \: bd = bc + cd \\ so \: we \: can \: write \: that \\ 67 = 3x - 2 + 4x + 13 \\67 = 3x + 4x - 2 + 13 \\ 67 = 7x + 11 \\ 7x = 67 - 11 \\ 7x = 56 \\ x = \frac{56}{7} \\ x = 8 \\ thankyou[/tex]

Answer:

[tex]\huge\boxed{\sf 22}[/tex]

Step-by-step explanation:

By looking at the line segment, we get to know that:

BD = BC + CD

Given that:

BD = 67

BC = 3x - 2

CD = 4x + 13

Solution:

Put the givens in the above equation made.

67 = 3x - 2 + 4x + 13

67 = 3x + 4x - 2 + 13

67 = 7x + 11

7x = 67 - 11

7x = 56

Divide both sides by 7

x = 56 / 7

x = 8

Now, Finding BC:

= 3x - 2

Put x = 8

= 3(8) - 2

= 24 - 2

= 22

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

The number is 15

Step-by-step explanation:

Assigning variables:

s = Sonali, f = father

Setting up an equation:

f = 5 + 3s

Solving with substitution:

(44) = 5 + 3s

39 = 3s

s = 13

Checking the work:

44 = 5 + 3(13)

44 = 5 + 39

44 = 44
