Either -1/2 or -0.5. Either will work
1+8=9
9*40=360

1:8=40:320
Answer:
A
Step-by-step explanation:
because 631 is the total miles, the equation will be equal to 631.
Second, because he is driving at 61 miles/hour, 61 will be the rate, so
61x+b=631
sense he already drove 221 miles, that will be where b is, so
61x+221=631
-6+3=-3
-6-3=-9
so -3 and -9
