55 blue or red marbles,
55-22 = 33 blue marbles
bag1+bag2= 2525
bag1=.4
33/55=.6 blue marbles
bag 2=.6
so it is 40% that U choose bag 1
Answer:
The common difference is 2
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 = -5
a10 = 13
Substituting n=10 a10=13 and a1 =-5
13 = -5 +d (10-1)
13 = -5 +9d
Add 5 to each side
13+5 = -5+5 +9d
18 = 9d
Divide each side by 9
18/9 = 9d/9
2 =d
Answer:
6 + 10v – 8w = 62
Step-by-step explanation:
Given the expression
6 + 10v – 8w
as
substituting the values in the expression
6 + 10v – 8w = 6 + 10(4) - 8(-2)
= 6 + 40 + 16
= 62
Well,
Given that
,
We can rewrite the equation like,

Now use,
which implies that 
That means that,

By def
therefore 
So the fraction now looks like,

Which is equal to the identity,

Hope this helps.
