Use the interactive number line to find the sum.

-5.5 + 3.7 =

where is you number line, well I had the same question and I answered this

R = (-1) + (-2) = -3

S = (-4) + (1) = -3

T = (-6) + (-3) = -9

Step-by-step explanation:

f is the midpoint of

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

12= 9x

divide by 9

12/9 =

1.3 =x
