Answer:
Step-by-step explanation:
correct equation is n - 31 = 52
Answer:
34+(-12) =22
Step-by-step explanation:
because they said that adding numbers but they didn't said that negative Or positive. so i took those numbers
To factor both numerator and denominator in this rational expression we are going to substitute
with
; so
and
. This way we can rewrite the expression as follows:
Now we have two much easier to factor expressions of the form
. For the numerator we need to find two numbers whose product is
(30) and its sum
(-11); those numbers are -5 and -6.
and
.
Similarly, for the denominator those numbers are -2 and -5.
and
. Now we can factor both numerator and denominator:
Notice that we have
in both numerator and denominator, so we can cancel those out:
But remember than
, so lets replace that to get back to our original variable:
Last but not least, the denominator of rational expression can't be zero, so the only restriction in the variable is
What's up? the answer is 1/2
6 sides in which 3 are odd. 1,3,5
3/6 or 1/2 chance of rolling odd
