Answer:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is 
mm^2
Step-by-step explanation:
For this case we know that we have a coin with a diamter of 
, and by definition the radius is given by:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is mm^2
Esay, first what you have to do us move -6 to the right side and now you will have 3y=-3x+6, what you want to do next is to divide 3y by both sides and your final answer is y=-x+2, hope this helps.
Step-by-step explanation:
Just consider the inequalities an equal sign and do the usual way of solving:
8x - 6 > 12 + 2x
8x - 2x > 12 +6
6x > 18
x > 3
*The only rule that you need to remember is that when you multiply or divide a negative number on both sides, then the inequality sign would be reverse.*
Example:
-x + 3 > -2
-x > -2-3
-x > -5
Multiplying both sides by -1:
x < 5

Anya's current age is 30 years and Cole current age is 27 years
Let x represent Anya current age and y represent Cole current age.
Anya is three years older than her brother, Cole. Hence:
x = y + 3
x - y = 3 (1)
In 11 years, the sum of their ages will be 79. Hence:
(x + 11) + (y + 11) = 79
x + y = 57 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 27
Anya's current age is 30 years and Cole current age is 27 years
