It's a false statement.

On the left side,  28 - 0.3 = 27.7

On the right side,  0.7 - 12 =  -11.3

The equation says that  27.7  is equal to  -11.3 , but it's not.

By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.
Maslowich

Answer:

430

Step-by-step explanation:

<u>Given :-</u>

  • By selling a watch on 400 and 460’. Loss and profit happened respectively.
  • The loss and profit are equal.

And we need to find out the CP .So ,

<u>Let :- </u>

  • CP be x
  • Profit and Lost be y .

<u>According to the Question :- </u>

:\implies 460 = x + y <em>( Profit)</em>

:\implies 400 = x - y <em>( Loss)</em>

<u>Adding both :- </u>

:\implies 460 + 400 = x + y + x - y

:\implies 860 = 2x

:\implies x = 860/2

:\implies x = 430

<u>Hence the Cost price of the watch is 430 .</u>

¿CUAL ES EL PERIMETRO DE UN RECTANGULO SABIENDO QUE SU ANCHO ES 3/4 DEL LARGO Y BEL LARGO MIDE 2,55M?
m_a_m_a [10]

Answer:

Perímetro = 8.925 metros

Step-by-step explanation:

La formula del perímetro de un rectángulo es:

perímetro = 2(ancho + largo)

en este caso:

p = 2(a+b)

a = 3b/4

b = 2.55m

a = ancho del rectángulo

b = largo del rectángulo

entonces:

sustituyendo el valor de la segunda ecuación

p = 2((3b/4)+b)

p = 2((3b/4)+(4b/4))

p = 2(7b/4)

p = 14b/4

p = 7b/2

p = 7*2.55/2

p = 8.925m

Describe how to solve the inequality 3x+4&lt;13 using algebra tiles
vladimir1956 [14]

The solution is x < 3.

Solution:

The given expression is 3x + 4 < 13.

To solve the given inequality.

3x + 4 < 13

Subtract 4 tiles on both sides of the inequality.

⇒ 3x + 4 – 4 < 13 – 4

⇒ 3x < 9

Divide by 3 tiles on both sides of the inequality.

⇒ \frac{3x}{3} =\frac{9}{3}

⇒ x < 3

Hence the solution is x < 3.
