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:
If i did this right the answer would be 69
I converted the inches to feet (might be my first mistake)
so i get 2.5 X 1 X 1 to get 2.5
i then multiply that by 62.4 to get 156
then 225-156 = 69

Answer:
b
Step-by-step explanation:
convert 2 1/2 hours into minutes to be easier to work with
15 / 150 = 10 minutes
every 10 minutes he pots a plan.
there are 210 minutes in 3 1/2 hours
210 / 10 = 21
