Seven times the number of quarters in a coin collection is the same as three times the number of quarters increased by 20. How many quarters in the collection

5

Explanation:

Let P be the number of quarters in a coin collection.

Seven times the number of quarters in a coin collection is expressed as;

7×P

= 7P... (1)

Also three times the number of quarters can be expressed as 3P. If this value is increased by 20, the resulting expression will be;

3P+20 (increment means addition)...(2)

If the two expression are the same then equation 1 = equation 2 i.e

7P = 3P + 20

7P-3P = 20

4P = 20

P = 20/4

P = 5

Therefore the number of quarters in the coin collection is 5

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
