What is 3 1/2 - 2 5/7 and show the work

Hunter-Best [27]

$3 \frac{1}{2} -2 \frac{5}{7} = \frac{(3\cdot2)+1}{2} - \frac{(2\cdot7)+5}{7} = \frac{7}{2} - \frac{19}{7} \\\\= \frac{7\times 7}{2\times 7} - \frac{19\times 2}{7\times 2} = \frac{49}{14} - \frac{38}{14} \\\\= \frac{49-38}{14} =\boxed{\bf{\frac{11}{14}}}$

0.2x + (-0.9) + 1.7 = 9.6<br> 0.2x + 0.8 = 9.6

user100 [1]

Answer:44

Step-by-step explanation:

0.2x+(-0.9)+1.7==9.6

0.2x+0.8=9.6

Subtract 0.8 from both sides

0.2x+0.8-0.8=9.6-0.8

0.2x=8.8

Divide both sides by 0.2

0.2x ➗ 0.2=8.8 ➗ 0.2

x=44
