Answer:
The answer to your question is w = 1.2
Step-by-step explanation:
Data
Equation 7(w + 2) + 0.5w = 5
Expand 7w + 14 + 0.5w = 5
Simplify like terms (7w + 0.5w) + 14 = 5
7.5w + 14 = 5
Subtract 14 in both sides
7.5w + 14 - 14 = 4 - 15
Simplify
7.5w = - 9
Divide both side by 7.5 7.5/7.5w = 9/7.5
Simplify
w = 1.2
Answer:
Part A
The given numbers are 14.25 and 0.86
By multiplying the two numbers, we have;
14.25 × 0.86 = 12.255
By adding the two numbers, we have;
14.25 + 0.86 = 15.11
Therefore, addition gives the greatest solution because one of the number is a fraction less than one
Part B
By dividing the two numbers (Dividing the larger number, 14.25 by the smaller number 0.86), we have 14.25/0.86 ≈ 16.57
Therefore, dividing the larger number by the smaller fraction gives a solution larger than the solution found in part A because the larger number multiplied by (1 - the inverse smaller fraction number) is larger than the value of the smaller (fraction) number
