The least possible value of 8x - 13 when 9 is less than or equal to 3/4 + x is;

53.

According to the question;

9<=3/4 + x.

Therefore,

9 -3/4 <= x

8 1/4 <= x

Therefore, x >= 33/4.

The least possible value of x is therefore, 33/4

The expression 8x -3 becomes;

8(33/4) -13

=66 - 13

= 53.

Therefore, the least possible value of 8x - 13 is;

53.

What is the difference of 9 5/9 - 6 5/6

zhuklara [117]

Hi there, first we change the mixed numbers into improper fractions, 9 5/9=86/9 and 6 5/6=41/6. Second, we solve the problem now. 86*6-41*9÷9*6, 516-369/54=147/54. Third, we simplify 147/54 into 49/18. Fourth, we make 147/54 into a mixed number. 147/54 as a mixed number is 2 13/18
