Answer:
41.4 degrees
Step-by-step explanation:
Find cos x by dividing both sides of this equation by 4:
cos x = 3/4 = 0.75
Using a calculator's inverse cosine function, find x:
arccos 0.75 = 0.723 radian, or
0.723 rad 180 deg
--------------- * ------------- = 41.4 degrees
1 pi rad
The answer is 5663588 for your question
Well if she added three blue and four red originally, and is now using 16 red then we would divide 16 by the original four. Which means to get the number of blue we are gonna end up multiplying by four. So three times four is twelve. Which means she would use 12 blue and 16 red to get the same color she got with 3 blue and 4 red earlier. The equation, lets use x for blue and y for red, would be 4(3x + 4y) = desired color
Answer:
13.92
Step-by-step explanation:
Answer:
first I would combine terms which would give me
-4x-7=-7-4x
then I would get the variable on each side of the equal sign
0=0
lastly I would verify the solution
infinite solutions
Step-by-step explanation:
combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions
