I only need help with number 9 plz
Varvara68 [4.7K]

Answer:

<h2>Letter C</h2>

Step-by-step explanation:

If we look on the number line we see that there is a point on -3, another point on -1, 2, and 7.

These points tell us our answer, but the question states it doesn't have to be in any order.

As we look at answer A we see -3, 1, 2, and -7. That's incorrect since there is no positive 1 nor an -7.

As we look at answer B we see -3, 7, 1, and -2. That's incorrect since there is no positive 1, and not a -2.

As we look at answer D we see -2, 3, 1, and 7. That's incorrect since there is no positive 2, no positive 3, and no negative 1.

C has to be the correct answer since it's the only answer left and has the 4 numbers that are on the number line.

Therefore, the correct answer is C.

Best of Luck to you.

Serhud [2]

Answer:B

I think we are in the same class lol

Step-by-step explanation:448 divided by 14= 32

448 divided by 16= 28

B=speed of boat in water

Y= Speed of current

B+y=32

B-y=28

32 + 28 =60

60 divided by 2 = 30

32 -30 =2

B=30

Y=2
