Answer:
Step-by-step explanation:
Divide both sides by 2
x - 1 = 5
Add 1 to both sides
x - 1 + 1 = 5 + 1
Combine
x = 6
Answer:
(16 x − 4 , x² + 5x) + 6
if we simplify it
but i don't know what your asking exactly..
Answer:
The measure of minor arc GFC is 
Step-by-step explanation:
we know that
In a circle the sum of the major arc plus the minor arc is equal to 360 degrees
see the attached figure to better understand the problem
Let
x------> the major arc GEC
y-----> the minor arc GFC
so
we have
substitute in the equation and solve for y
X=invested at 10%12000-x=invested at 15% .10x+ (.15)(12000-x)=1440 ;; 12% of the total amount is 12% of $12000. .10x + 1800-.15x=1440
-0.05x=-360x=7200 12000-x=4800 $7200 at 10%=$720$4800 at 15%=$720 That is $12000 earning $1440, and that is 12%
