If 5 pens cost 95 cents, that means that each pen cost 95/5 = 19 cents each. So a dozen will cost:
dozenCost = 12*19 = 228 cents

Step-by-step explanation:
Given that;
n=6 , m=2 , z1 is the average of the elements of x , and z2 is the average of the first three elements of x minus the average of fourth through sixth elements of x
So, Let d=n∧28, d′=n∧22.
We have nd=10, nd′=20n
so
n=10d=20d′nwhenced=2d′.
On the other hand, d is a divisor of 28, and above shows d′ is, too. As it is also a divisor of 22, the only possibilities are d′=1, d′=2, corresponding to d=2, d=4.
However, if d=2, n=20, and 20∧28=4, not 2. So the only solution is d=4, and n=40.
Answer: D
Step-by-step explanation:
Answer:
-1.5 or -6/4
Step-by-step explanation:
Im assuming the equation is 4x+6=0
1.) subtract the 6 from each side.
4x= -6
2.) you need to isolate the X, so divide the 4 from each side.
X= -6/4 or -1.5
