Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs. For example, in 2x + 3 > 5, We may subtract 3 from both sides, 2x > 2 Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-) For example, 2 < 6 But, -2 > -6
And when you interchange a fraction E.g. 3/4 > 2/3 But, 4/3 < 3/2
d₂ = distance covered each day in the next 5 days From the question, Given: d₁ = 3 miles = 7/2 miles T = 5 Days d₂ = 4 miles = 17/4 miles Substitute these values into equation 1 D = [ (7/2)×5]+ [ (17/4)×5] D = 17.5+21.25 D = 38.75 miles
no less than means greater than or equal to because -5/9 is the lowest it can go (nothing less than), meaning that number or higher. 5 times a number k is just 5 times k, which is 5k to the inequality is
