Answer: d=12

Step-by-step explanation:

$\displaystyle\\\frac{3d-2}{8} =-d+16\frac{1}{4} \\\\\frac{3d-2}{8} =-d+\frac{16*4+1}{4} \\\\\frac{3d-2}{8} =-d+\frac{64+1}{4} \\\\\frac{3d-2}{8} =-d+\frac{65}{4}$

Multiply both parts of the equation by 8:

$\displaystyle\\3d-2=(-d+\frac{65}{4} )(8)\\\\3d-2=-8d+65*2\\\\3d-2=-8d+130\\\\3d-2+2=-8d+130+2\\\\3d=-8d+132\\\\3d+8d=-8d+132+8d\\\\11d=132\\$

Divide both parts of the equation by 11:

$d=12$

Describe how the product of 0.4 x 2 would look on a ten-square grid. The product would have (blank) squares shaded out of 10.

lawyer [7]

Answer:

The answer would be 0.8, 8 squares filled.

Step-by-step explanation:

This is because 0.4*2 is 0.8 and that out of a grid of 10 means that 8 cubes would be shaded.
