Answer:
D
Step-by-step explanation:
The information from the first equation gives you the information needed for the second. To solve the first equation you must rearrange the equation to isolate X. In order to do that you can first move the 3 to the other side of the equation by subtracting it from both sides (5x + 3 - 3 = 4 - 3) and then simplify that to (5x = 4 - 3) and further to (5x = 1). Then to move the 5 you must divide both sides by 5 so you get (5x/5 = 1/5) which can be simplified to (x = 1/5)
From this you can use the X value and input it into the second equation
Y = -3(1/5) and then solve for Y.

$6 is 20% of a $30 haircut
To get 20/10 as a mixed number you would have to take 20 and divide it by 10. Once you do that your answer should be 2.
Answer:
Area of a Circle = πr²
R=Diameter/2
=21mm
=π(21)²
=1385.44mm²
To the nearest whole number
= 1385mm²
The answer is in mm². It may differ if the given answer is in m². You can get this by converting your radius to meters. This is done by dividing 21mm by 1000.
