Answer:
x = 3/4
y = 5/4
Step-by-step explanation:
Step:
Substitute−x+2 for y in y=3x−1:
y=3x−1
−x+2=3x−1
−x+2+−3x=3x−1+−3x(Add -3x to both sides)
−4x+2=−1
−4x+2+−2=−1+−2 (Add -2 to both sides)
-4x = -3
x=3/4
Step: Substitute x into the original equation
y=-3/4 + 2
y=5/4

Find the volume of the Cone. Use 3.14 for . Round your answer to the nearest hundredth ( 2 decimals). Show your work in this question, and record your answer in the next question.
Answer:
2,616.67cm³
Step-by-step explanation:
Find the diagram attached
volume of the cone = πr²h/3
r is the radius = 10cm
h is the height = 25cm
Substitute
V = 3.14(10)²*25/3
V = 314*25/3
V = 7850/3
V = 2,616.67cm³
Hence the volume of the cone to the nearest hundredth is 2,616.67cm³

Answer:
105
Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.
Hope this helps! Thanks for brainliest! :D

What is 3 (2x + 4) = 12?
Answer:
Hi!!
The answer is = 0
Step-by-step explanation:
1. Distribute
3(2+4)=12
6+12=12
2. Subtract 12 from both sides of the equation
6 + 12= 12
6 + 12 − 12 = 12 − 12
3.Simplify
part A. 6 + 12 − 12 = 12 − 12
6x = 12 - 12
part B. 6x = 12 - 12
6x = 0
