Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation. So remember to solve this problem, addition property of equality is adding from both sides of an equation to the same number doesn't change the equation.
First, add 3 from both sides.
Solve.
As a result, the correct answer is x=7.

Answer:
Heyy
Step-by-step explanation:
Lets Price of article is 100
Dep value after 1 year =100−
100
100×10
= 90
Dep. value after 2 year =90−
100
90×10
=81
Dep. value after 3 years =81−
100
81×15
=68.85
Total Dep. =100−68.85 = 31.15%
There are two red suits of 13 cards ... 3 face cards in a suit and 2 red suits, so there are 6 red face cards. Thus, ... A five card hand is drawn from a standard deck of 52 cards.
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4
