Step-by-step explanation:

$P(2, 13)= (x_1, y_1) \:\&\: Q(17, 1)=(x_2, y_2)$

length of segment PQ

$= \sqrt{ {(x_1 - x_2)}^{2} + {(y_1 - y_2)}^{2} } \\ = \sqrt{ {(2 - 17 )}^{2} + {(13 - 1)}^{2} } \\ = \sqrt{ {( - 15 )}^{2} + {(12)}^{2} } \\ = \sqrt{225 + 144} \\ = \sqrt{369} \\ = 19.2093727 \\ \approx \: 19.21 \: units$

kwasi thought of a number, multiplied it by7/2 and added 16 to the results.if the final answer was 30.what number did he think o

ziro4ka [17]

Answer:

Step-by-step explanation:

represent the number he thought of with x

$\frac{7}{2} x + 16 = 30$

multiply through with the LCM which is 2
$2 \times \frac{7}{2}x + 16 \times 2 = 30 \times 2$
$7x + 32 = 60$
$7x = 60 - 32$
$7x = 28$
$\frac{7x}{7} = \frac{28}{7}$
$x = 4$
