DIA [1.3K]

Answer:

Step-by-step explanation:

Given, 

$\frac{1}{ {6y}^{ - 2} }$

Since,

${x}^{ab} = {( {x}^{a} )}^{b}$

Hence,

$= \frac{1}{ {( {6y}^{2} )}^{ - 1} }$

Since,

$\frac{1}{ {x}^{ - 1} } = x$

Hence,

$= {6y}^{2} (ans)$

The sum of a 3 digit number and a 1 digit number is 217. The product of the numbers is 642. If one number is between 200 and 225

algol [13]

Let, the numbers be "x" and "y". Consider "x" as the triple digit number.
Now, according to the question,
x + y = 217..........................equation (1)

x * y = 642............................equation (2)

Now,
Taking equation (2),
x * y = 642
y = 642 / x..................................equation (3)

Now, Taking equation (1),
$x+y=217$

Substituting the value of y from equation (3), we get,

$x+ \frac{642}{x} =217$

$\frac{x *x+642}{x} =217$

$x^{2} +642 =217*x$

$x^{2} +642 =217x$

$x^{2} +642-217x =0$

$x^{2} -217x+642 =0$

$x^{2} -3x-214x+642 =0$

$x(x-3)-214(x-3)=0$

$(x-3)(x-214)=0$

Using zero product property,
EITHER,
x - 3 = 0
x = 3
OR,
x - 214 = 0
x = 214
Since, "x" is the triple digit number, x = 214.
Now,
Taking equation (2),
x * y = 642
Substituting the value of "x" in the equation, we get,
(214) * y = 642
y = 642 / 214
y = 3

So, the numbers are 214 and 3.

Find the value of X in the figure below.

marissa [1.9K]

Answer:

Step-by-step explanation:

Since ∠C = 50° (sum of angles in a triangle), ΔABC is isosceles (Converse of Base angles theorem) meaning AB = AC (Def. of isosceles Δ) which means x = 8.
