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
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.
Increased number of protons in the nucleus.
The product obtained by division is the Quotient
Division is a mathematical operation where a number is divided by another number to find out how many times the second number is contained within the first number. The result of a division operation is called the quotient.
There are several factors contributing to the rise in asthma cases, including increased air pollution, exposure to allergens, changes in diet, and lifestyle factors such as decreased physical activity and increased stress levels. Additionally, better awareness and diagnosis of asthma may also play a role in the increasing number of reported cases.
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.
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
if the quotient of -20 and 4 is decreased by 3
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
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7
11-9=v
87
It has decreased.
Increased
If a fraction's denominator is increased, the number gets smaller. If a fraction's denominator is decreased, the number gets bigger.
. This is same as half of r.
