Answer 1

Answer:

$a) \frac{( - 21)}{8} = \frac{x}{56} \\ Cross \: multiply \\ 8x = ( - 21) \times 56 \\ x = \frac{( - 21) \times 56}{8} \\ x = ( - 21) \times 7 \\ x = ( - 147)$

$b) \frac{13}{( - 17)} = \frac{104}{x} \\ Cross \: multiply \\ 13x = 104 \times ( - 17) \\ x = \frac{104 \times ( - 17)}{13} \\ x = 8 \times ( - 17) \\ x = ( - 136)$

$c) \frac{x}{95} = ( - 6) \\Cross \: multiply \\ x = ( - 6) \times 95 \\ x = ( - 570)$

$d) \frac{( - 85)}{x} = ( - 17) \\ Cross \: multiply \\ ( - 17)x = ( - 85) \\ 17x = 85 \\ x = \frac{85}{17} \\ x = 5$
