Answer 1

Respuesta:

a. 77/3 ; b. 1 ; c. 1/54 ; d. 37/7

Explicación paso a paso:

a.

$\\ a + ( - \frac{8}{3} ) = 23 \\ a = 23 + ( \frac{8}{3} ) \\ a = \frac{69}{3} + \frac{8}{3} = \frac{77}{3}$

b.

$\\ 2y + ( - \frac{5}{4} ) = 0.75 \\ 2y = \frac{75}{100} + \frac{5}{4} \\ 2y = \frac{75}{100} + \frac{125}{100} \\ 2y = \frac{200}{100} \\ \\ y = \frac{200}{200} = 1$

c.

$\\ 18x = \frac{1}{3} \\ x = \frac{1}{3(18)} = \frac{1}{54}$

d.

$\\ m - 5 = \frac{2}{7} \\ m = \frac{2}{7} + 5 \\ \\ m = \frac{2}{7} + \frac{35}{7} = \frac{37}{7}$
