Answer:
Step-by-step explanation:
n/3 - 2 = 4 Add 2 to both sides
n/3 - 2 + 2 = 4+2 Combine
n/3 = 6 Multiply both sides by 3
3*n/3 = 6 * 3
n = 18
Company 1: (24 + 26 + 28 + 23 + 21) / 5 (this is how many numbers added together) = 24.4
Company 2: (6 + 32 + 9 + 31 + 21) / 5 = 19.8
Company 3 (15 + 15 + 15 + 15 + 15) / 5 = 15
Company 4: (13 + 10 + 45 + 12 + 15) / 5 = 19
Company 1 has the longest average commute time per employee.
Answer:
Step-by-step explanation:
Givens
Circle: 3 grams Number: 1 right hand side Number LHS: 2
Square: 2 grams Number: 2 Number LHS: 5
Triangle: x Number: 5 Number LHS: 2
Formula
Mass RHS = Mass LHS
Solution
3*1 + 2*2 + 5x = 3*2 + 5*2 + 2*x Combine
3 + 2 + 5x = 6 + 10 + 2x
5 + 5x = 16 + 2x Subtract 5 from both sides
5-5+5x = 16-5 + 2x Combine
5x = 11 + 2x Subtract 2x from both sides
3x = 11 Divide by 3
x = 11/3
As you can see, I'm not getting any of the answers that you have provided. Ask your teacher how it was done. (The method used is correct).
