The difference between set of whole numbers and a set of integers is that:
Whole numbers = {0, 1, 2, 3, 4, 5...}
Integers = {..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}
If we name contents of the first set as n, in the second set you can have 2n-1 numbers (because we count 0 only once in both sets).
Answer:
x-3=6
Step-by-step explanation:
Answer:
(7,5)
Step-by-step explanation:
{2x + 4y = 34
{4y = 27 - x
2x + 27 - x = 34
x=7
4y = 27 - 7
y = 5 so the answer is ( 7,5)
Answer:
= 10
Step-by-step explanation:
Multiplication first:
(-3 + 8 x 2 - 3) =
(-3 + 16 - 3)
Simplify the rest:
(-3 + 16 - 3)
= (13 - 3)
= 10
