x = .5x - 4.
Get all of the x's on one side:
x - .5x = .5x - .5x -4 ---> .5x = -4
Multiply each side by 2.
x = -8
Written algebraically, the equation is (2/A)=4.The first step is to move the variable A from the denominator. To do this, multiply both sides of the equation by A:A*(2/A)=4*AThe A in the denominator on the left is canceled out and we are left with:2=4*ATo solve for A divide both sides of the equation by 4:2/4=ATwo over four simplifies to one half, which equals A:1/2=A
3y + 2/4 =7 First, you subtract 2/4 (1/2) from both sides, resulting in 3y = 13/2 (6 and a half) Then, you multiply both sides by 1/3 (which is the same as dividing by 3), giving you y=13/6.

L = P/2 - W.

Better formatting is cos(2x+20)=-0.5
If you mean: y = 3/4x-0.5 then the perpendicular equation could be y = -4/3x-5

x/2 + 6 = 2x (Multiply by 2) x + 12 = 4x (Subtract x) 12 = 3x (Divide by 3) x = 4 (Check it) 4/2 + 6 = 2 x 4 2 + 6 = 8

L = P/2 - W.

This gives us the equation: A = hb/2 + c To solve for c, we simply subtract hb/2 from each side! A - hb/2 = c c = A - hb/2
Half correct because x = 2 and y = 6
The statement that represent that is one - half a number is 267.
To write a multiplication equation with a half as a factor, you can express it in the form ( a \times \frac{1}{2} = b ), where ( a ) is the other factor and ( b ) is the product. For example, if you want to multiply 4 by a half, you would write it as ( 4 \times \frac{1}{2} = 2 ). This equation shows that half of 4 equals 2.
