Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.

Please help 1. another term for adding money to an account is
zzz [600]
<span>Payment. While payment is the sum of money paid in exchange for something either goods and services; the money can be credited (or added) into an account directly without making direct payment. We can also credit our account which is also payments. The most efficient way of building a savings is having a set minimum or percentage for saving whichever is greater. Sometimes we may need to save more than our "set minimum" especially when we earn more. The higher we earn the more our set minimum pales in comparison to what we ought to save. On the other hand if we have a set percentage it would also need to be raised higher when we earn more, but saving whichever is greater ensures that we make the best and most efficient savings decision at any period in time.</span>

If cosA=4/5 and cosB=3/5 then find a,b,c
aliya0001 [1]

Answer:

a = 3, b = 4, c = 5

Step-by-step explanation:

Assuming we're working with a right triangle, where c is the hypotenuse, then using the definition of the cosine being the adjacent side over the hypotenuse, then we know:

a = 3, because it is the side adjacent to B

b = 4, because it is the side adjacent to A

c = 5, because it is the denominator in bot fractions

This of course assumes that there is no additional ratio in place.  For example, if the lengths were instead 8, 6 and 10 respectively, then the cosines given would still be 4/5 and 3/5.  Truthfully these only tell relative sizes of the sides, and not their absolute sizes.
