Answer:
x=14
Step-by-step explanation:
2(3x-4)=5x+6
first get rid of the parentheses by multiplying the 2
6x-8 = 5x+6
put like terms on one side of the equation. Start with the 5x, move it to the left side
(6x-8)-5x = (5x+6)-5x
x-8 = 6
Again, put like terms on one side of the equation. Move the 8 to the right side
(x-8)+8 = 6+8
=> x = 14
B)
4x - 3 = 2(x-1)
Start again by getting rid of the parentheses to make it a clean equation... aka distribute the 2:
4x-3 = 2x - 2
Move the like terms to one side of the equation. Start with x.. move 2x to the left:
(4x-3)-2x = (2x-2)-2x
=> 2x-3 = -2
Move the like terms to one side of the equation.Now move the -3 to the other side:
(2x-3)+3 = -2+3
=> 2x=1
Lastly, divide by 2 on both sides to find out what x is:
(2x)/2=1/2
=> x = 1/2
..so no, Charlie was incorrect.
Answer: 2x-1
Step-by-step explanation:
x+2+x-3
2x-1
Answer: The answer is D. Trapezoid.
Step-by-step explanation: As shown in the attached figure, a rectangular pyramid ABCDE is drawn. We are slicing this rectangular pyramid parallel to the base BCDE at the points F, G, H and I.
We can clearly see from the figure that upper half of the sliced figure will be similar to the pyramid BCDE and the lower sliced figure will be a trapezoid. These are the three-dimensional figures.
Also, the sliced two-dimensional figure FGHI will be a rectangle, because
the pyramid is a rectangular one and so, FI=GH, FG=HI and all the angles are right angles.
Thus, the resulting two-dimensional figure will be a rectagle.
Answer:
13.7
Step-by-step explanation:
a^2+b^2=c^2. 9.2^2 +x=16.5^2 x=16.5^2-9.2^2. x=root187.61 which is 13.7.
Hope this helps plz mark brainliest :D
