Question

Write expressions for the following:
i) 7 added to thrice a number x.
ii) 4 taken away from z.
iii) sum of two times p and 5 times q.
iv) 5 more than the quotient of m divided by n.

Answer 1

Answer:

I) 7+3x

×= -7/3

ii)-4z

z=4

iii)p²+q²

iv)5n/m

Answer 2

Answer:

i) 3x+7

ii) z-4

iii) 2p+5q

iv) {(mxn)+5}/n

Step-by-step explanation:

i) Since 'x' is supposed as the unknown number, the thrice of it will be '3x' and if 7 is added to it, the answer becomes 3x+7.

ii) Since 4 is taken AWAY FROM 'z', 4 should be subtracted from z i.e. z-4.

iii) Two times p = 2p

   Five times q = 5q

Therefore, their sum = 2p+5q

iv) As the quotient = m,

   The remainder = 5

   The dividend = (mxn)+5

The final answer = {(mxn)+5}/n
