N + (n+1) + (n+2) + (n+3) = 90
if n is the first number, then the next number is 1 more than n, the next number is 2 more than n, etc.
Simplify the above expression:
4n + 6 = 90
4n = 84
n = 21
n+1= 22
n+2 = 23
n+3 = 24
The appropriate inequality would be 4x + 19 ≤ -26
Answer:
A?
Step-by-step explanation:
Answer:
the -81 is not a sequenced
Step-by-step explanation:
To simplify 2x+3-x+5, we can first group x together,then calculate:
Therefore the answer is x-2.
Hope it helps!
