Answer:

Hence, the value of "x" is -4.

Step-by-step explanation:

\sf \leadsto \dfrac{2x + 1}{3} + 1 = \dfrac{x - 4}{6}

\sf \leadsto \dfrac{2x + 1 + 3}{3} = \dfrac{x - 4}{6}

\sf \leadsto \dfrac{2x + 4}{3} = \dfrac{x - 4}{6}

\sf \leadsto 6(2x + 4) = 3(x - 4)

\sf \leadsto 12x + 24 = 3x - 12

\sf \leadsto 12x - 3x = -12 - 24

\sf \leadsto 9x = -36

\sf \leadsto x = \dfrac{-36}{9}

\sf \leadsto x = -4

<u>Hence, solved!!</u>

Answer:

x=-4

Step-by-step explanation:

\frac{2x +1 }{3}  + 1 =  \frac{x - 4}{6}

\frac{2x + 1 + 3}{3}  =  \frac{x - 4}{6}

6(2x + 4) = 3(x - 4)

2(2x + 4) = x - 4

4x + 8 = x - 4

4x - x =  - 4 - 8

3x =  - 12

x =  \frac{ - 12}{3}

x =  - 4

ABC est un triangle rectangle en B.<br> On donne : AB = 7:BC = a et AC = a +5.<br> Calcule a
Afina-wow [57]

Answer:

Step-by-step explanation:

salut :

en utilisant le theorem de Pythagore on obtient :

AC²= AB² + BC²

(a+5)² = 7²+a²

a²+10a+25 = 49+a²

10a+25 =49

10a =24

donc : a = 24/10 = 12/5 = 2.4 unit

How are perpendicular lines and interesting line alike? How are they different?
sleet_krkn [62]
Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...

They are different because perpendicular lines cross one another in a specific way.  The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing.  It could be at any angle.

Length of a rectangle is 7 less than 3 times it’s width. Area is 40cm^2. Find dimensions URGENT
sasho [114]
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !

Suppose there is a 20% chance of rain on Monday and a 40% chance of rain on Tuesday. Assuming the weather on successive days is
nadya68 [22]

Answer:

a. 52%

b. 40%

Step-by-step explanation:

Let A represents the event of raining on Monday and B represents the event of raining in Tuesday,

Then according to the question,

P(A) = 20% = 0.2,

P(B) = 40% = 0.4,

Here, A and B are independent events,

So, P(A∩B) = P(A) × P(B),

⇒ P(A∩B) = 0.2 × 0.4 = 0.08

We know that,

P(A∪B) = P(A) + P(B) - P(A∩B)

a. The probability it rains on Monday or Tuesday, P(A∪B) = 0.2 + 0.4 - 0.08

= 0.52

= 52%

b. The conditional probability it rains on Tuesday given that it rained on Monday,

P(\frac{B}{A})=\frac{P(A\cap B)}{P(A)} = \frac{0.08}{0.2}=0.4 = 40\%
