I don’t know how you do 17.1 divided by 0.9.
andreyandreev [35.5K]
The answer is 19


work :

1-multiply the numbers by a submultiple of 10 to remove the decimal points.
17.1 \times 10 = 171 \\  \\ 0.9 \times 10 = 9

2-

now do the division :
171 \div 9 = 19

so the answer is 19



note: there is no need to get it back to decimal number unless you multiply just one of the numbers or multiply the numbers with different submultiples of 10



good luck

20 = -d + 6
Sphinxa [80]

ok so rearrange things so that it says 6-d=20, then subtract six from each side to get -d=20-6, then subtract 6 from 20 to get -d=-14, then multiply both sides by -1 to get rid of the negative sign in front of the d since a variable cannot be a negative thus making your answer -14 or letter D. :) ❤❤❤❤

hope this helps
