Question

1. Translate each phrase into an algebraic

expression.
a) seven less than twice a number
b) four more than half a value
c) a number decreased by six, times
another number
d) a value increased by the fraction
two thirds

Answer 1

Explanation:

a) 2x - 7

because "seven less than twice a number". if it says "seven less twice a number" it would be 7 - 2x.

b) x/2 + 4

c) (x - 6)y

the comma after "six" is important. without it it should be x - 6y

d) x + 2/3
