(6 1/2+2 3/4)-1.5*(4.5 divided by 0.5)

 - (4 1/4)

Solution:

(6 1/2 + 2 3/4) - 1.5*(4.5/0.5)=

(6 0.5 + 2 0.75) - 1.5*(9)=

(6.5+2.75) - 13.5=

(9.25) - 13.5=

- 4.25=

-(4 0.25)=

-(4 1/4)

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
