The number is eleven
ANSWER
First of all we want the unknown # or x to be left by itself so ?=x
x-4=8+(x/5)
-8 -8
x-12=x/5
*5 *5
5x-60=x
-5x -5x
-60=-4x
/-4 /-4
15=x
I believe it is 15 not 11
substitute x for 11 and 15...
try- 11-4=8+(11/5)
11-4=10+(1/5)
7=10+(1/5) ???
try- 15-4=8+(15/5)
11=8+3
11=11
it works this way

Colligative properties are physical or chemical properties?
Purely physical: depends on the number of particles rather than on the kind of them.The number influences e.g. the boiling point elevation (decreased volatility), osmotic pressure (increased osmolality), etc.
How do chemical proprties of isotopes compare?
an isotope is a different form of that element. They just have different mass numbers/ atomic mass. Therefore having the same characteristics of the atom except for an increased/decreased number of neutrons. Isotopes have the same atomic number as each other.
Why does the size of d-block elements decrease gradually in the periodic table?
As increase in proton number, the attraction from nucleus towards electrons increased. This will pull the electrons stongly. So, the size/ atomic radius decreased across the d-block.
Why do not action potentials occur during the repolarization phase?
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
What is increasing atomic number?
Increased number of protons in the nucleus.
The quotient of a number and -9 increased by 10 is 11?
A quotient is the number obtained when one number is divide by another. 11 decreased by 10 is 1. The only number that can be paired with -9 to obtain a quotient of 1 is -9.
A certain number decreased by 2 is equal to 7 increased by the quotient of the same number and 4 what is the number?
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
When the quotient of 3 times a number and 4 is decreased by 3 the result is 9?
if the quotient of -20 and 4 is decreased by 3
A certain number decreased by 4 is equal to 8 increased by the quotient of the same number and 5 and 7 or 11 are not the answer What is the number?
So let's call the number we are looking for x. x-4 is the number decreased by 4 quotient of the number and 5 is x/5 so x-4=8+ x/5 we have 5x-20=40+x and 4x=60 so x=15 Let's try it? 15-4=11 8+15/5=11
A certain number decreased by 4 is equal to 8 increased by the quotient of the same number and 5 What is the number?
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7
11 decreased by the quotient of nine and a number?
