Answer:

The correct answer is A. No, because 3 + 7 = 11 is not true.

Step-by-step explanation:

Just like the answer says, if x =3, then that would mean that 3 + 7 = 11. Since

3 + 7 =10, this statement is not true.

Therefore, the correct answer is A.

Hope this helps! :D

Which expression results in a sum or difference of five and six fifty fourths? (3 points) a eight and seven ninths minus three a

Genrish500 [490]

Answer:

a) eight and seven ninths minus three and four sixths

Step-by-step explanation:

The required result is $5\frac{6}{54}$

$8\frac{7}{9} -3\frac{4}{6}\\\\=\frac{79}{9} -\frac{22}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{474-198}{54} \\\\=\frac{276}{54}\\\\=5\frac{6}{54}$

$6\frac{8}{9} -1\frac{5}{6}\\\\=\frac{62}{9} -\frac{11}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{372-99}{54} \\\\=\frac{273}{54}\\\\=5\frac{3}{54}$

$4\frac{1}{6} +1\frac{1}{9}\\\\=\frac{10}{9} +\frac{25}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{60+225}{54} \\\\=\frac{285}{54}\\\\=5\frac{15 }{54}$

$3\frac{3}{6} +2\frac{4}{9}\\\\=\frac{22}{9} +\frac{21}{6} \\\\Simplifying\ the\ expression:\\\\=\frac{132+189}{54} \\\\=\frac{321}{54}\\\\=5\frac{51 }{54}$
