It stands for whatever you choose it to stand for.
d = 2
It is a linear equation in one unknown, d.
To find the value of (2c + 4d) when (c = 30) and (d = 8), substitute the values into the expression. This gives you (2(30) + 4(8) = 60 + 32 = 92). Therefore, (2c + 4d = 92).
D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60
1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8
4d÷8
4d + 7 = -15 so 4d = -22 so that d = -5.5
4d (d + 5)
The D stands for the width, shoes come in diferent widths and lengths. They come in D to 4D, 4D being wider.
d = 2
5+3 = 4d 4d = 8 Divide both sides by 4 to find the value of d: d = 2
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
It is an equation and the value of d is 2
4d x d x d = 4d3
It is a linear equation in one unknown, d.
To find the value of (2c + 4d) when (c = 30) and (d = 8), substitute the values into the expression. This gives you (2(30) + 4(8) = 60 + 32 = 92). Therefore, (2c + 4d = 92).
D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60
