We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:


\frac{S}{356} = \sqrt{d}


Square both sides to get rid of the square root:


\frac{S^2}{126736} = d


Now plug the known value of the speed to find the distance:


d = \frac{140^2}{126736} = \frac{19600}{126736} \approx 0.15465


So the closest answer is the last one: d=0.155km

Solve this system of linear equations. Separate
alex41 [277]

Answer:

y = 7 and x =3

Step-by-step explanation:

use elimination method

so we gonna eliminate y first

9x = 1 - 4y

-7x = -7 + 4y

7| 9x = 1 - 4y

9| -7x = -7 + 4y

63x = 7 - 28y

-63x = -63 + 36y

add eqtn 1 to eqtn2

you will get

0 = -56 + 8y

56 = -56 + 56 + 8y

56 = 8y

56÷8 = 8y÷ 8

7 = y

also eliminate x as we have done wth y

4| 9x = 1 - 4y

4| -7x = -7 + 4y

36x = 4 - 16y

-28x = -28 + 16y

add the two equations

u will get

8x = -24 + 0

8x = -24

8x÷8 = 24÷ 8

x = 3
