Answer: -25
Since x=-3, y=6, and z=-4 you have to plug those numbers into the corresponding varibale in the equation. So 3x becomes 3(-3) because x=-3, 2y becomes 2(6) because y=6 and z becomes just -4. The whole equation comes to 3(-3)- 2(6)+(-4)= -25
Its $136.27 + $23.50w = $253.77
Answer:
33.92
Step-by-step explanation:
Lets list the differences in the above list : these are 2 5 11 23 47:
call this list a
This last list has difference 3 6 12 24 (list b) so next number in this list is 48 and next number in list a is 47+48 = 95
In the original sequence therefore the next number is 89 + 95 = 184
so the list a and b are 2 5 11 23 47 95 List a
3 6 12 24 48 List b
The next number in list b is 96 and the next in list a is 96 + 95 = 191
so next number in sequence in question = 184 + 191 = 375
Next number in list b is 192 and next in list a = 191 + 192 = 383
So last number in sequence = 375 + 383 = 758
Next 3 numbers are 184, 383 and 758 answer
Sorry but I cant figure out the explicit rule at moment. I'll try and come back with it.
The four numbers are: -4, -2 ,0, 2 Answer.
How do you solve this: the sum of four consecutive even integers is equal to least of the integer
Solution: Let the numbers be n, n+2, n+4 and n+6.
Their sum = 4n+12 = n or
3n+12 = , or
3n = -12,
n= -4
therefore we get -4, -2, 0, 2
The four numbers are: -4, -2 ,0, 2 . Answer.
