Answer:
-2-4
Step-by-step explanation:
When a + sign is followed by a negative number, it's the same as a - sign followed by a positive number
If it is a mixed number it should be 509 7/10
Answer:
= 4n + 2
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence, that is
d = 10 - 6 = 14 - 10 = 18 - 14 = 22 - 18 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 6 and d = 4, thus
= 6 + 4(n - 1) = 6 + 4n - 4 = 4n + 2
Answer:
p = 7
Step-by-step explanation:
(2+10i) - (7+pi) = (-5+3i)
2-7 = -5
10i - pi = 3i
Subtract 10i from each side
-pi = 3i - 10i
-pi = -7i
Divide by -i
p = 7
That means p = 7
Answer:
350 - 170 - 120 = r
Step-by-step explanation:
Identify the variable:
r = number of red pens
The total amount of pens ordered is 350 when adding all three colors of pens. This means we must add all of the colored pens to find the total number of pens, 350.
Write this as an equation:
170 + 120 + r = 350
Rewrite the equation to find r:
350 - 170 - 120 = r
