c: -1.5 - (-3.6)=
d: 7/12 - 5/12 =
e: 3/7 + 5/21 +8/9=
f : -2/3 - 1/2 =
answer in a fraction form!

i think it is c, not positive though

step-by-step explanation:

yes

step-by-step explanation:

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
