12 - d > 8. Solving inequalities
Jlenok [28]

Answer:

d<4  I might not be right but I think this is correct

Step-by-step explanation:

Simplify both sides of the inequality.

−d+12>8

Subtract 12 from both sides.

−d+12−12>8−12

−d>−4

Divide both sides by -1.

\frac{-d}{-1} >\frac{-4}{-1}

d > 4

What is 0.003is 1/10 of
Whitepunk [10]
0.003 is 1/10 of 0.03.

Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplying by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.
