The difference between a number and 8 is 11

quester [9]

Answer:

The difference between 19 and 8 is 11.

Step-by-step explanation:

Given:

The difference between a number and 8 is 11

Find the number.

Solution:

Let the unknown number be $=x$

The difference between the unknown number can be written as:

$x-8$

We are given that the difference =11

So we can write the equation to find $x$ as :

$x-8=11$

Using additive property to solve for $x$

Adding 8 to both sides to isolate $x$ on one side.

$x-8+8=11+8$

∴ $x=19$

∴ The unknown number = 19

MatroZZZ [7]

Answer:

Step-by-step explanation:

$\dfrac{a^{m}}{a^{n}}=a^{m-n} \ if \ m > n\\\\\\
\dfrac{a^{m}}{a^{n}}=\dfrac{1}{a^{n-m}} \ if \ n > m\\$

$\dfrac{16r^{6}z^{3}}{8r^{2}z^{6}}=\dfrac{2r^{6-2}}{z^{6-3}}\\\\
=\dfrac{2r^{4}}{z^{3}}$

What is the distance between the points (2, 5) and (5,7)?

Svetlanka [38]

Answer:

$\sqrt{13}$

Step-by-step explanation:

The distance formula that gives the distance between two points is given as:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Plugging in our given points, we get:

$d=\sqrt{(5-2)^2+(7-5)^2},\\d=\sqrt{3^2+2^2},\\d=\sqrt{9+4},\\d=\fbox{$\sqrt{13}$}$ .
