Each student gets 2 1/7 cookies
15 divided by 7 is 2.14 or 2 1/7
Answer:
A
Step-by-step explanation:
<h3>Numerator</h3>
(3x)(3x) = 9x^2
√9x^2 = 3x
Numerator = 3x
<h3>Denominator</h3>
√18y^2 = √18 · √y^2
√18 = 3√2
√y^2 = y
3√2y
Denominator = 3√2y
Now we need to rationalize the denominator, and get rid of the square root on the bottom
*

7x +7y + 7 hope this helps as an expansion :)
19/x=sin 20
19/sin 20=x
x=55.5522836
