Answer D and A
Step-by-step explanation:
-7 x -3 = 21 that gives you 21 = 5x-24 then you need to add 24 to both sides as it’s negative so 21+24=45. -24+24=0 that gives you 45 =5x. 45/5=9. 5x/5=x. X=9
You would have to round all the repeating decimals to the nearest hundredths or tenths or thousandths
A.) 0.78 = 78/100 you can reduce on this answer so it would be 39/50
