Answer:
|x − 37,500| ≤ 4,500
Step-by-step explanation:
salary - 37,500 can be up +4500 or as negative -4500
as much as means less than or equal to
We use absolute values to indicate this
|x − 37,500| ≤ 4,500
Answer:
48,24,30
Step-by-step explanation:
Let, the length of second side be x
A/c to question,
first side (a) = 2x
second side (b) = x
third side (c) = x + 6
Perimeter of ∆ (p) = 102
And,
Perimeter of ∆ = a + b + c
102 = 2x + x + x + 6
102 - 6 = 4x
96 = 4x
x = 96/4
x = 24
Now,
first side = 2*24 = 48
second side = 24
third side = 24 + 6 = 30
