Step-by-step explanation:
The product and the quotient of the decimal numbers are both negative
(because when multiplying/dividing, and ur signs are different, then ur answer will be negative)
The sum of the decimal numbers is positive
(because when adding, if the signs are different, u subtract and take the sign of the larger number)
The difference of the decimals is positive
(because ur subtracting a negative...4.58 - (- 0.145) = 4.58 + 0.145...and that equals a positive)
3/7s= -8
⇒ s= -8/ (3/7) (inverse operation)
⇒ s= -8* (7/3)
⇒ s= (-8* 7)/3
⇒ s= -56/3
⇒ s= -18 2/3
Final answer: s= -18 2/3~
