Answer:
She bought 2 long sleeve shirts and 4 t-shirts
Step-by-step explanation:
Let number of long sleeves = x
Let number of t-shirts = y
x+y=6
∴y=6-x
14x+4y=44
14x+4(6-x)=44
14x+24-4x=44
10x=20
x=2
y=6-x
=6-2=4
ANS: She bought 2 long sleeve shirts and 4 t-shirts
You just take your rule y=4x-1 and plug it in for your y ex:-4(-5)-1=19 like that just plug it in for others
X = 2.1 x tan(37)
x = 1.58 = 1.6
Answer: The answer is 
Step-by-step explanation: Given that the area of the whole circle is represented by the expression
We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.
Now, if 'r' represents the radius of the circle, then we have
Thus, the area of the outer ring is
