Answer: 26
Step-by-step explanation: In this problem we have 3 consecutive even numbers whose sum is 84 and it asks us to find the smallest number.
Consecutive even numbers can be represented as x, x + 2, and x + 4.
Since the sum of these is 84, our equation reads
x + (x + 2) + (x + 4) = 84.
Simplifying on the left we get 3x + 6 = 84.
Subtract 6 from both sides and we have 3x = 78.
Divide both sides by 3 and x = 26.
So our smallest number is 26.

Step-by-step explanation:
Exterior angle of a triangle is equal to the sum of opposite interior angles
13b - 48 = (9b - 47) + (b + 44)
Add the like terms
13b - 48 = 10b - 3
Add 48 to both the sides
13b - 48 +48 = 10b - 3 +48
13b = 10b + 45
Subtract 10b from both sides
13b - 10b = 10b + 45 - 10b
3b = 45
Divide both sides by 3
3b/3 = 45/3
b = 15

Answer:
Yes
Step-by-step explanation:
4.05 can be written as 4.050 in 3-place decimal or 3 digits.
Compare:
4.05 = 4.050
4.050 < 4.055
Since 5 > 0 for last digit, the Inequality is true.
