Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

$\frac{OK}{KY} =\frac{OC}{RY}$

$\frac{12}{24} =\frac{OC}{96}$

$24OC=1152$

$OC=48$

$\frac{KC}{RK} =\frac{OK}{KY}$

$\frac{50}{RK} =\frac{12}{24}$

$12RK=1200$

$RK=100$

Musya8 [376]

Answer:

22.5 miles per hour

Step-by-step explanation:

<u>Given system of equations</u>

5(s-w)=900

4(s+w)=900

<u />

<u>Set equations equal to each other</u>

5(s-w)=4(s+w)

5s-5w=4s+4w

s-5w=4w

s=9w

<u>Solve for w using the substitution s=9w</u>

4(s+w)=900

4(9w+w)=900

4(10w)=900

40w=900

w=22.5

Therefore, the speed of the wind is 22.5 miles per hour

$\textbf {Let's Solve :}$

<h3>Question 1 :</h3>

$\textsf{4x - 3 = 2x +7}$

$\textsf{4x -2x = 3 +7}$

$\textsf{2x = 10}$

$\textsf{x=5}$

<h3>Question 2 :</h3>

$\sf{2x + 6 = 7 \times 14}$

$\sf{2x + 6 = 98}$

$\sf{2x = 98-6}$

$\sf{2x = 92}$
