It takes 7 days to finish harvest wheat (75/12=6.25) and 7 to harvest corn (62.5/10=6.25). So the answer is 7
Answer: 3 1/6
Step-by-step explanation:
-1 1/3 would be converted into an improper fraction which is -4/3.
-4 1/2 in an improper fraction is -9/2 but you need to get the same denominators.
You change -4/3 to -8/6, and -9/2 to -27/6
You then do -8/6 - (-27/6) so you are actually adding cause of the two negative signs!
You should get 19/6 which is 3 1/6 in mixed form.
Answer:
Step 1: Simplify both sides of the equation.
−7+3(8n−8)=8(7+3n)
−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)
−7+24n+−24=56+24n
(24n)+(−7+−24)=24n+56(Combine Like Terms)
24n+−31=24n+56
24n−31=24n+56
Step 2: Subtract 24n from both sides.
24n−31−24n=24n+56−24n
−31=56
Step 3: Add 31 to both sides.
−31+31=56+31
0=87

Answer:
B. The lengths of two of the triangle's sides and the measure of the angle between them
Step-by-step explanation:
The usual formulation of the law of cosines is something like this:
c² = a² +b² -2ab·cos(C)
where 'c' is the side opposite angle C, and 'a' and 'b' are the other two sides. That is, to use this formula directly, one needs two side lengths and the measure of the included angle.
_____
<em>Additional comment</em>
One can use the law of cosines to solve a triangle when any two sides and one angle are known. The use of the formula will give a quadratic in the unknown side length, if it is not the side opposite the known angle. As with the law of sines, if the angle is opposite the shorter of the two given sides, there may be two solutions for the length of the third side.
