Answer:
9/20
Step-by-step explanation:
Find the common denominator:
1/5 and 1/4
1/5*4/4 = 4/20 and 1/4*5/5 = 5/20
So we can add them together now
4/20 + 5/20 = 9/20
so 9/20 of her customers order fish or chicken
So the equation is n/4-4=14
then you +4 to both sides
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
+4 +4
then to check your work
72/4-4=14
so N=72
Hope I helped :)
Answer:
1/4
Step-by-step explanation:
The probability of it being a cardinal is the number of cardinals / the total number of possible birds the hawk could eat.
There are 3 + 5 + 4 = 12 total birds near the bird feeder.
There are 3 cardinals.
So the probability is 3/12 = 1/4 that the cardinal is eaten!
(m+4)(m+1)
=m^2+5m+4........
