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.
STEPS:
Place compass point on the vertex of the angle (point B).
Stretch the compass to any length that will stay ON the angle.
Swing an arc so the pencil crosses both sides (rays) of the given angle. ...
Place the compass point on one of these new intersection points on the sides of the angle.
Answer:
The answer is 3, 6.
Step-by-step explanation:
The numbers in the top rows on the left side of the equation is 1, 4 and 2, 2.
1, 4 + 1, 2 = (1 + 2), (4 + 2) = 3, 6
Answer:
14 7/12
Step-by-step explanation:
You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.
The answer should be ∆ABD is congruent to ∆CBD by reflection.
