Which property of equality could be used to solve x - (-6) = 18?

The property of equality that can be used to solve x - (-6) = 8 is the addition property of equality.

Step-by-step explanation:

When subtracting a negative in an equality problem, you would have to use the reverse operation which would be the addition property of equality. Subtracting a negative may seem like adding a positive but when it comes to equality property problems, you still use the opposite operation.

x - (-6) = 18

   +-6     +-6

x = 12.

12 - (-6) = 18.

146 days

step-by-step explanation:

1. (365*2)/5 =

730/5 =

146 days

2. 365/5=

73*2   = 146

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
