Answer:
3
Step-by-step explanation:
Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11
Answer:
θ ≈ 40°
Step-by-step explanation:
Since, sinθ = 
cosθ = 
tanθ = 
In the picture attached,
Measures of adjacent side and opposite side of the triangle have been given. Therefore, tangent rule will be applied in the given triangle.
tanθ = 
θ = 
θ = 39.56
θ ≈ 40°
Answer: I assume this ques was formatted like this originally. 4/10 = 2. If so the answer is 5 making the second fraction 2/5. Let me know if this is not the case. Hope this helps!
(1/2x5x6)x2+(11x5)x2=140
