Question

: Write the following using numbers, literals and arithmetic operations,
(a) 7 less than
(b) 3 more than quotient of x by y
(c) 5 times x added to 2 times y
(a) 7 less than x means 7 is subtracted from x.​

Answer 1

(a) 7 less than x

7 less than x means 7 is subtracted from x

So, we write x - 7

(b) 3 more than quotient of x by y

Quotient of x by y can be written as x/y

3 more than x/y is x/y + 3

(c) 5 times x added to 2 times y

5 times x is 5x, 2 times y is 2y,

5 times x added to 2 times y is 5x + 2y
