Question

Give expressions in the following cases.
(a) 11 added to 2m
(b) 11 subtracted from 2m
(c) 5 times y to which 3 is added
(d) 5 times y from which 3 is subtracted
(e) y is multiplied by—8
(f) y is multiplied by — 8 and then 5 is added to the result
(g) y is multiplied by 5 and the result is subtracted from 16
(h) y is multiplied by —5 and the result is added to 16.

Answer 1

The expressions for the given cases are as follows:

(a) The expression will be (11+2m) because we have to replace the word 'added to' with the sign of addition.

(b) The expression will be (2m-11) because the number to be subtracted is 11.

(c) The expression will be (5y+3) because the word 'times' in mathematics denote multiplication and the word 'added' is replaced by its sign, +.

(d) The expression will be (5y-3) because 3 is subtracted from 5 times y.

(e) The expression will be (-8y).

(f) The expression will be (-8y+5).

(g) The expression will be (16-5y) because 5y is the result that is to be subtracted.

(h) The expression will be (-5y+16).
