Answer:
£25
Step-by-step explanation:
total distance travelled per week = 2 * 7.5 * 5 = 75
amount of fuel used = 75/30 = 2.5 gallons = 11.375 litre
cost of fuel = 11.375 * 1.14 = 12.9675
total cost = 5(2.5) + 12.9675 = 25.4675 ~~ 25
Rational because it can be written as a ratio (fraction)
Since x, 2x, 3x contain numbers and variables, it takes two steps to find the LCM. Find the LCM for the numerical part 1; 2; 3; then find the LCM for the variable part x¹ ; x¹; x¹.
The LCM is the smallest number by which all numbers are divided without leaving a remainder.
- List the prime factors of each number.
- Multiply each factor the greatest number of times that occurs in any of the numbers.
The number 1 is not a prime number because it only has one positive factor, which is itself.
not cousin.
Since 2 has no divisors other than 1 and 2.
2 is a prime number.
Since 3 has no divisors other than 1 and 3.
3 is a prime number.
The least common multiple LCM of 1,2,3 is the result of multiplying all the prime factors the greatest number of times that appear in each term.
2 × 3
Multiply 2 by 3.
6
The factor for x¹ is x itself.
x¹ = x
The Least Common Multiple LCM of x¹ ; x¹; x¹ is the result of multiplying all the prime factors the greatest number of times that appear in each term.
x
The LCM for x;2x;3x is the numerical part 6 multiplied by the variable part.
6x ====> Answer
Since ur using i as a imaginary unit, the answer is -11/2 and simplify that and u get -5 1/2.
