Twice the sum of consecutive numbers n and n+1 is 510. What is the smaller number and the larger number?
1 answer:
Answer:
n is smaller, n + 1 is larger
Step-by-step explanation:
First, make the equation.
2(n + n+1) = 510
Then, simplify.
2(2n + 1) = 510
Distribute.
4n + 2 = 510
Solve.
n = 127
The smaller number is n (127) and the larger number is n + 1 (128).

Step-by-step explanation:
those are the only ones with two terms being added
Subtract 40 from both sides
-vp+40-40<95-40
Simplify
-vp<55
Multiply both sides by -1 (reverse the inequality)
(-vp) (-1) > 55 (-1)
Simplify
vp> -55
Divide both sides by v
vp ÷ v > -55 <span>÷ v

Simplify
p> -55 <span>÷ v </span>
