Answer:

  7x - 19 = x + 16

Step-by-step explanation:

Once you get over your aversion to "word problems", you find that the translation from English is not hard.

"Seven times a number" is 7x.

Nineteen less than that is 7x-19.

"16 more than the number" is x+16.

"Is" means "is equal to," so you have ...

  7x -19 = x +16 . . . . . . . matches the first choice

_____

<em>Additional comment</em>

The 11-digit number at the top is intended to impart an energy that may help with an aversion to word problems. The effect is subtle and often takes numerous repetitions over time.

Naddika [18.5K]

Answer:

Step-by-step explanation:

sides =8 cm, 17 cm and 15 cm

Area of triangle by Hero's Formula,

S=a+b+c/2

S=17+8+15/2

S=40/2

S=20

A=\sqrt{s(s-a)(s-b)(s-c)}

A=\sqrt{20(20-17)(20-8)(20-15)}

A=\sqrt{(20)(3)(12)(5)}

A=\sqrt{3600}

A=60 cm^{2}

sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya​
madreJ [45]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = \frac{d}{2}

 = \frac{18}{2}

 = 9 \ cm

Height,

h = 20 cm

As we know,

⇒  Area of a cone = \frac{1}{3} \pi r^2 h

On substituting the given values in the above formula, we get

⇒                            = \frac{1}{3}\times 3.14\times (9)^2\times 20

⇒                            = \frac{1}{3}\times 3.14\times 81\times 20

⇒                            = 3.14\times 27\times 20

⇒                            = 1,695.6 \ cm^3
