Answer:
102
Step-by-step explanation:
Each triangle will have a perimeter of 3. When joined, the outside triangles will have 2 sides showing, or 2 inches. The middle 98 will only have one free side, or one inch. This means that 98*1 + 2*2 = 102
The equation would be 2x+3 so when you plug it in it's 2(-2)+3 which simplify to -4+3 which is -1
Answer:
N = Noel's Salary
N - 512.75 = Robert's Salary (512.75 less than Noel)
3(N-512.75) = John's Salary (3 times Robert's Salary)
Step-by-step explanation:Total Salary = 47645.25 = N + (N - 512.75) + 3(N-512.75)
47645.25 = 2N - 512.75 + 3N - 1538.25
47645.25 = 5N - 2051
49696.25 = 5N
9939.25 = N (Noel's Salary)
Robert's Salary = 9939.25 - 512.75 = 9425.50
