Answer:
its either 12.5 or 32
Step-by-step explanation:
Here is your answer:
1 1/2 = 3/2
7 × 3 = 21
8 × 2 = 16
Divided to equal 
<--- Real answer:
The reason why she multiplied her answer wrong, she also "kept her original numerator and denominator."
Hope this helps!
Answer:
-4 sqrt(7)/7
Step-by-step explanation:
csc theta = -4/3
csc theta = hypotenuse / opposite side
hypotenuse = 4
opposite = 3
Using the pythagorean theorem
a^2 + b^2 = c^2
3^2 + b^2 = 4^2
9+b^2 = 16
b^2 = 16-9
b^2 = 7
Taking the square root
sqrt(b^2) = sqrt(7)
b = sqrt(7)
We are in the third quadrant so only tan and cot are positive
that means the x and y values are "negative" so a = -3 and b = - sqrt(7)
sec theta = hypotenuse / adjacent
= 4/ - sqrt(7)
rationalizing
-4 sqrt(7)/ sqrt(7)* sqrt(7)
= -4 sqrt(7)/7
Yes, 13•150=1950 and then 11•60=660 so combined they equal 2610
