Which inequalities??
A+n=7B
A-n=3B
2A=10B
Try to see if you can find the answer from there? If not, I will give you the solution. (I still think 17/7 is the correct answer though.)
Agreed! I was going to post one but yours is already detailed!
1. 6-8-10 is a pythagreon triple so the area would be (6*8)/2 = 48/2 = 24. But if you don't know that 6-8-10 is 3-4-5 multiplied by 2, you can use the pythagreon theorem to find the third side: sqrt(6^2 + 8^2) = sqrt(36+64) = sqrt(100) = 10 and find the area the same way from that.
2. The triangle sum theorem states the three angles in a triangle sum to 180 degrees. Since we know two angles, the third one must be: 135+30+x=180 ⟹ 165+x=180 ⟹ x = 180-165 ⟹ x = 15. Therefore angle BAC = 15 degrees.
I got 1920 @SportzGuy2310 when I expanded it using the binomial theorem.
Assume:
the # of yellow marbles is x
the # of green marbles is 2x
the # of blue marbles is 3x
the # of white marbles is 4x
x+2x+3x+4x=180
10x = 180
x = 18
the # of blue marbles = 3x = 3(18) = 54 marbles
And your solution is incorrect, the correct answer is 940. You would have to use multiplicative inverses in your solution.
What is CRT + MMI?
Good job!
