First, subtract 0.6 from both sides of the numbers and then simplify
Then multiply all terms by the same value to eliminate fraction denominators which gives us 2.8
So, n = 2.8

450/25=18; 18x10=180. therefore the answer is B: 180 inches
They are spaced about 0.030 miles apart or 53.33 yards apart. Just divide 1 mile by 33 and get your answer. :) Hope I helped!
Answer:Robert's minimum age is 11 years.
Step-by-step explanation:
Let x represent George's age.
Let y represent Edward's age.
Let z represent Robert's age.
George is twice as old as Edward. It means that
x = 2y
Edward's age exceeds Robert's age by 4 years. It means that
z = y - 4
If the sum of the three ages is at least 56 years, it means that
x + y + z ≥ 56 - - - - - - - - - - 1
Substituting x = 2y and z = y - 4 into equation 1, it becomes
2y + y + y - 4 ≥ 56
4y - 4 ≥ 56
4y ≥ 56 + 4
y ≥ 60/4
y ≥ 15
z = y - 4 = 15 - 4
z ≥ 11
