Number of kms a car can run per litre petrol = 16 km
Quantity of petrol = \(\frac{11}{4}\)
Number of kms a car can run run for \(\frac{11}{4}\) litre petrol = \(\frac{11}{4}\) × 16 = 44 km
It will cover 44 km distance by using 2\(\frac{3}{4}\) litres of petrol.
Write equations for the following statements:
(i) The sum of numbers x and 4 is 9.
(ii) 2 subtracted from y is 8.
(iii) Ten times a is 70.
(iv) The number b divided by 5 gives 6.
(v) Three-fourth of t is 15.
(vi) Seven times m plus 7 gets you 77.
(vii) One-fourth of a number x minus 4 gives 4.
(viii) If you take away 6 from 6 times y, you get 60.
(ix) If you add 3 to one-third of z, you get 30
