<span>The word CALCULUS contains
2 C's + 1 A + 2 L's + 2 U's + 1 S = 8 letters, in all.
The number of distinct permutations of all these 8 letters
taken together is
... ( 8! ) / [ (2!) (1!) (2!) (2!) (1!) ]
= [ 8 · (7!) ] / 8
= 7 · (6!)
= 7 ( 720 )
= 5040 ........................................... . </span>
Its a lot easier to do 1.200 - .200. Than to do 1.248- .239. How I see it, estimating always gives you something to fall back on or to help see if your exact answer is accurate
Answer:
y = -3
Step-by-step explanation:
{y = x/2 - 4
y = 1 - 2 x
Substitute y = x/2 - 4 into the second equation:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
In the second equation, look to solve for x:
{y = x/2 - 4
x/2 - 4 = 1 - 2 x
Add 2 x + 4 to both sides:
{y = x/2 - 4
(5 x)/2 = 5
Multiply both sides by 2/5:
{y = x/2 - 4
x = 2
Substitute x = 2 into the first equation:
{y = -3
x = 2
