Answer:
2
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
let
8 = n ⇒ 8 = 
, that is
2³ = ( equate exponents )
n = 3
and let
( 
) = n ⇒ = 
, that is
= ( equate exponents )
n = - 1
then
8 + ( )
= 3 + (- 1)
= 3 - 1
= 2
Answer:
5/21
Step-by-step explanation:
1/7 + 2/21 = ?
lcd of 7 and 21 is 21 so;
( 2/21 x 1/1) + 1/7 x 3/3) = 5/21
Answer:
0.4
Step-by-step explanation:
0.2 is too small, and everything above 1.0 is too big, so by default, must be 0.4
Answer:
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.
Answer:
A. A linear pair is two adjacent, supplementary angles.
Step-by-step explanation:
from the description,
< ABD = 
, so that;
< ABD + <DBC = 
+ <DBC =
<DBC = -
= 
Thus,
<FBE = < ABD = (vertically opposite angles)
<ABF + <FBE = 
(supplementary angles)
<ABF + =
<ABF = -
= 
The statement that justifies why <ABF measures is a linear pair is two adjacent, supplementary angles.
