If a = 3, b = 1, and c =-1, what does (b + c) - (c-a)
equal?
4.
F.
G.
3
H.
0
J. – 2
K. – 4

4

Step-by-step explanation:

a=3

b=1

c=-1

(b + c) - (c-a)

(1+(-1))-((-1)-(3))

Note

+*-= -

+*+=+

-*-=+

So

(1-1)-(-1-3)

0-(-4)

4

(1 - 1) - (-1 - 3)

0 + 4 = 4

Step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137
