Whats the answer to 1/2(5×-8)=-9
REY [17]

Answer:

I do not know if that x is a multiply sign or a variable so I'm going to answer both

If the x is a multiplication sign then the answer is -20 = -9

If the x is a variable then the answer is x = -2

Step-by-step explanation:

1/2(5 * -8) = -9

(1 * 5 * -8)/2 = -9

(5 * -8)/2 = -9

-40/2 = -9

-20 = -9

-20 ≠ -9

1/2(5x - 8) = -9

1(5x -8)/2 = -9

(5x - 8)/2 = -9

2((5x - 8)/2) = -9 * 2

2(5x - 8)/2 = -9 * 2

5x - 8 = -9 * 2

5x - 8 = -18

    +8    +8

------------------

5x = -10

x = -10/5

x = -2

Divide 5 3/4 ÷ 1 1/2
Kipish [7]

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

What is a mixed number ?

  • A bit represented with its quotient and remainder is a mixed bit. For illustration,21/3 is a mixed bit, where 2 is the quotient, 1 is the remainder.
  • So, a mixed bit is a combination of a whole number and a proper bit. A mixed bit, also called a mixed number, is a whole number and a bit together.
  • The bit is written to the right of the whole number.
  • A mixed number is formed by combining three corridor a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper bit that makes the mixed number.

The required mixed number is 3\frac{5}{6} . The calculations are attached with the solution as an image.

An electric bulb is sold in a box measuring 5 cm by 4 cm by 4 cm. If the shopkeeper receives them in a carton measuring 50 cm by
katen-ka-za [31]

Answer:

250

Step-by-step explanation:

Bulb box and carton both are of cuboidal shape.

<u>For bulb </u><u>box</u><u> </u><u>the </u><u>d</u><u>imensions</u><u> </u><u>are:</u>

  • l = 5 cm, w = 4 cm, h = 4 cm

  • V_{Bulb\: box} =lwh

  • \implies V_{Bulb\: box} =5(4)(4)

  • \implies V_{Bulb\: box} =80\: cm^3

<u>For </u><u>Carton </u><u>the dimensions are</u><u>:</u>

  • l = 50 cm, w = 20 cm, h = 20 cm

  • V_{Carton} =lwh

  • \implies V_{Carton} =50(20)(20)

  • \implies V_{Bulb\: box} =20,000\: cm^3

To find the number of bulbs packed in the carton, divide the V_{Carton} by V_{Bulb\: box}

  • Number \:of \:bulbs =\frac{V_{Carton}}{V_{Bulb\: box}}

  • \implies Number \:of \:bulbs =\frac{20,000}{80}

  • \implies Number \:of \:bulbs = 250

So, 250 bulbs will be packed in one carton.

almond37 [142]

Answer:

A. 3x^2 + 4 = 52

     3x^2 = 52 - 4

     3x^2 = 48

       x^2 = 48/3

       x^2 = 16

        x    = \sqrt{16}

        x = 4

B. x^2 - 121 = 0

     x^2  = 121

       x = \sqrt{121}

       x = 11

C. (b + 4 )2 = 49

    2b + 8 = 49

    2b  = 49 - 8

     2b = 41

        b = 41/2
