Answer:
$10.80
Step-by-step explanation:
1. Multiply $12 X 10%
2. convert 10% to decimal = .10
3. 12 X .10 = 1.20
4. Subtract 1.20 from 12
5. 12-1.20 = 10.80
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:
B.
Step-by-step explanation:
process of elimination. the red dot is not a 1/4 of the number of lines, so it cant be 12.25, 13.625 is impossible because it has a value less than 13, and 12.625 is impossible as well because it has a value less than 12.5 therefore 12.375 is the best answer, and the only correct answer
(-8,-7) is in 3
(8,7) is in 1
(8,-7) is in 4
(-8,7) is in 2
