Question

In London today, four times the high temperature was more than twice the high temperature plus sixty-six. In interval form, what are the possible temperatures? O (-00, 33) 0 (-00, 33] O [33,00) 0 (33,00)

Answer 1

Let the temperature be x.

four times the high temperature will be expressed as:

4x

twice the high temperature plus sixty-six will be expresssed as:

2x+66

Hence if four times the high temperature was more than twice the high temperature plus sixty-six, this is expressed in inequality form aas:

4x > 2x+66

Solve the resulting inequality

subtract 2x from both sides:

4x - 2x> 2x+66 - 2x

2x > 66

Divide both sides by 2:

2x/2 > 66/2

x> 33

This means that the value of x will be greater than 33

Hence the possible temperatures will be all the temperature greater than 33
