Question

efetue:
$- \frac{5}{8} \div + \frac{3}{2} = \\ \frac{5}{8} - \frac{3}{2} = \\ 8\% \: de 52 = \\ 7(t - 3) = 2t + 5 =$

Answer 1

$\frac{5}{8} - \frac{3}{2} = \frac{2}{16}$
8% de 52=
52____100%
x______8%
100x=416
x=416÷100
x=4,16
$7.(t - 3) = 2t + 5 \\ 7t - 21 = 2t + 5 \\ 7t - 2t = 5 + 21 \\ 5t = 26 \\ t = 26 \div 5 \\ t = 5.2$
