Give expressions for the following cases.

(a) Rita scores x marks in Maths and 46 marks in English. What is her total score in Maths and English.

(b) The difference of x and 9 where x > 9.

$\text{(c) The product of}a\text{and}b\text{added to the difference of}a\text{and}(a>b).$

(d) One-half of a multiplied by the sum of x and y.

(e) The total distance travelled by a car in x hours at a constant speed of y km/h.

(f) The total number of eggs in n cartons if each carton contains k eggs.

Answer 1

$\text{(a) Total marks}=x+46$
$\text{(b)}x-9$
$\text{(c)}ab+a-b$
$\text{(d)}\frac{a}{2}\times (x+y)$
$\text{(e) Distance}=(x\times y)\text{Km.}$
$\text{(f) Number of eggs}=(n\times k)\text{eggs}$
