Answer:

\boxed{x =\frac{-3m-3}{2}}

Step-by-step explanation:

3m + 2x=-3

\sf Subtract \ 3m \ from \ both \ sides.

3m + 2x-3m=-3-3m

2x=-3-3m

\sf Divide \ both \ sides \ by \ 2.

\displaystyle \frac{2x}{2} =\frac{-3-3m}{2}

\displaystyle x =\frac{-3m-3}{2}

Answer:

x=\frac{-3-3m}{2}

Step-by-step explanation:

1st step: Subtract 3m from both sides. 3m+2x-3m=-3-3m

2nd step: Simplify. 2x=-3-3m

3rd step: Divide both sides by 2. \frac{2x}{2}=-\frac{3}{2}-\frac{3m}{2}

Final step: Simplify. x=\frac{-3-3m}{2}

Sutopa has 3/4 of the money Maneet has. Maneet has $18 less than Kim. Together, they have $286.40. How much money does each of t
anastassius [24]

Solving a system of equations we can see:

  • Sutopa has $73.20
  • Maneet has $97.60
  • Kim has $115.60

<h3>How much money each of them has?</h3>

First, let's define the variables:

  • S =  money that Sutopa has.
  • M = money that Maneet has.
  • K = money that Kim has.

We can write the system of equations:

S = (3/4)*M

M = K - $18

S + M + K = $286.40

First, we can rewrite the second equation to get:

K = M + $18

Now we can replace the first and second equations into the third one:

(3/4)*M + M + (M + $18) = $286.40

Now we can solve this for M:

M*(1 + 1 + 3/4) = $286.40 - $18

M = $268.40*(4/11) = $97.60

Now we can find the other two values:

K = M + $18 =  $97.60 + $18 = $115.60

S =  (3/4)*M =  (3/4)*$97.60 = $73.20

andreev551 [17]

Step-by-step explanation:

slope =  \frac{rise}{run}  =  \frac{y2 - y1}{x2 - x1}  \\  =  \frac{ - 7 - 13}{5 - ( - 3)}  \\  =  \frac{ - 20}{8}  \\ =   \frac{ - 2 \times 10}{2 \times 4}  \\  =  \frac{ - 10}{4}  \\  =  \frac{ - 2 \times 5}{ 2  \times 2} =  \frac{5}{2}

A zebra ran at a speed of 20 ft./s what operation should you to find the distance the zebra ran in 10 seconds
evablogger [386]
V (velocity) = distance / time

So distance = velocity x time = 20 x 10 = 200 ft.
