Answer:
86.16
Step-by-step explanation:
27+3÷ 3 +4-1+72.4-34.24+6-4+75÷5
PEMDAS
Multiply and divide first
3/3 is 1 and 75/5 = 15
Replace these into the equation
27+1 +4-1+72.4-34.24+6-4+15
Then add and subtract from left to right
31 +72.4-34.24+6-4+15
69.16+6-4+15
86.16
Answer:
1. Solution = (4,3) and they intersect.
2. Solution = Infinite, this means that the lines overlap each other constantly.
3. Equations = x + y=73 and 2.35x + 1.34y = 141.25

Step-by-step explanation:
Took the test and got 100%.
3/6 because there are 6 sides and there are 3 numbers that you want to roll. They are even numbers so if you want to roll half of the numbers but not the other half well you have 3/6
Answer:
10^2+2×2b×10+2b^2 = 100+40b+2b^2
Step-by-step explanation:
![\cos 90 \cos 30 + \sec^2 45 \sin 30 - \cos 270 \sin 180](https://tex.z-dn.net/?f=%5Ccos%2090%20%5Ccos%2030%20%2B%20%5Csec%5E2%2045%20%5Csin%2030%20-%20%5Ccos%20270%20%5Csin%20180)
But we know that
![\cos 90 = \cos 270 = \sin 180 = 0](https://tex.z-dn.net/?f=%5Ccos%2090%20%3D%20%5Ccos%20270%20%3D%20%5Csin%20180%20%3D%200)
and
![\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}](https://tex.z-dn.net/?f=%5Csin%2030%20%3D%20%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%20%5C%3A%5C%3A%5Ctext%7Band%7D%5C%3A%5C%3A%20%5Csec%2045%20%3D%20%5Csqrt%7B2%7D)
so this leaves us with just
![\sec^2 45 \sin 30 = (\sqrt{2})^2 \left(\dfrac{\sqrt{3}}{2} \right)= \sqrt{3}](https://tex.z-dn.net/?f=%5Csec%5E2%2045%20%5Csin%2030%20%3D%20%28%5Csqrt%7B2%7D%29%5E2%20%20%5Cleft%28%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%20%5Cright%29%3D%20%5Csqrt%7B3%7D)
