Answer:
A
Step-by-step explanation:
To complete the ratio, the number of good oranges would be 45.
You would then add 45 and 36 to get 81 oranges total
-10 − 8s − 1 = -7 − 4s
-10-1-8s= -7-4s
-11-8s= -7-4s
move -4s to the other side
sign changes from -4s to +4s
-11-8s+4s=-7-4s+4s ( combine like terms)
-11-4s=- 7
move -11 to the other side
-11+11-4s= -7+11
-4s= 4
divide both sides by -4
to get +s
to get s by itself
-4s/-4= 4/-4
answer:
s= -1
