Answer:

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

Step-by-step explanation:

Given

Ratio = 3:5

Q = -14

S = 2

Required

Which solution uses $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

From the given parameters;

$m:n = 2:5$

$m = 2\ and\ n = 5$

$x_1 = -14\ and\ x_2 = 2$

Substitute the above values in $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

This gives:

$(\frac{m}{m+n})(x_2 - x_1)+ x_1$

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

<em>From the list of given options, only option A uses the given form of the formula...</em>

Laura and Brent paddled a canoe 6 miles upstream in four hours. The return trip took 3 hours. What is the rate at which they pad

Harrizon [31]

P = paddling speed

C = speed of the current

Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)

4P - 4C = 6

3P + 3C = 6

12P - 12C = 18

12P + 12C = 24

Add the equations:

24P = 42. P = 42/24 = 1.75 mph

Subtract the equations:

-24C = -6

C = 0.25 mph
