Answer:
40.3
Step-by-step explanation:
Given (26.9 + 8.3) +5.1
First simplify the bracket
26.9 + 8.3= 35.2
Now add to 5.1 . We are adding because of the + sign attached to 5.1
35.2 + 5.1
40.3
Answer:
N = 2
Step-by-step explanation:
n - 3 = -1 Original
n ( -3 + 3 ) = ( -1 + 3 ) Add 3 on both sides
n = 2 Simplify
Check:
2 - 3 = -1 Replace
- 1 = -1 Solve
Correct!
Since 12.3 is less than 21 it will be a negative number. so just subtract 12.3 from 21 and put a negative symbol in front of the answer.
The Length of the Given Sign = 90 inches
The Side of the Triangle can be found by Pythagorean Theorem
⇒ (Side of the Triangle)² = 40² + 30²
⇒ (Side of the Triangle)² = 1600 + 900
⇒ (Side of the Triangle)² = 2500
⇒ (Side of the Triangle) = 50
⇒ Perimeter of the Given Sign = (4 × Side of Triangle) + (2 × Length)
⇒ Perimeter of the Given Sign = (4 × 50) + (2 × 90)
⇒ Perimeter of the Given Sign = (200 + 180) = 380 in
