Answer:

Step-by-step explanation:

let the no of people who share the meal be x

each member paid $17

total cost of meal=$51

so ur equation is

$17x=$51

x=$51/$17(here $ and $ also gets cancel)

x=3

therefore three menber shared the meal.

Note:when in multiplication when u transfers the number to other side it changes into mltiplication.For example

$17=$51

here $17 is multiplied with x and when we bring $17 to right hand side it divides $51.

Answer:

$17x = 51 \\ \frac{17x}{17} = \frac{51}{17} \\ x = 3$

Step-by-step explanation:

The error was that the learner subtracted both sides instead of dividing both sides. The student was supposed to divide both sides by 17 to get the answer.

Use Stokes' Theorem to evaluate S curl F · dS. F(x, y, z) = 5y cos(z) i + ex sin(z) j + xey k, S is the hemisphere x2 + y2 + z2

Alenkinab [10]

By Stokes' theorem, the integral of the curl of $\vec F$ across $S$ is equal to the integral of $\vec F$ along the boundary of $S$ , call it $C$ . Parameterize $C$ by

$\vec r(t)=2\cos t\,\vec\imath+2\sin t\,\vec\jmath$

with $0\le t\le2\pi$ . So we have

$\displaystyle\iint_S(\nabla\times\vec F)\cdot\mathrm d\vec S=\int_C\vec F\cdot\mathrm d\vec r$

$=\displaystyle\int_0^{2\pi}(10\sin t\cos 0\,\vec\imath+e^{2\cos t}\sin0\,\vec\jmath+2\cos t\,e^{2\sin t}\,\vec k)\cdot(-2\sin t\,\vec\imath+2\cos t\,\vec\jmath)\,\mathrm dt$
