Answer:

m =   - \frac{ \frac{t}{b} +  \frac{t}{r}  }{1 -  \frac{1}{v} }

Step-by-step explanation:

\frac{m}{v}  -  \frac{t}{b}  = m -  \frac{t}{r}  \\  \frac{m}{v}  -  \frac{t}{b}  +  \frac{t}{r} = m \\  -  \frac{t}{b}   +  \frac{t}{r}  = m -   \frac{m}{v}  \\  -  \frac{t}{b}  +  \frac{t}{r}  = m(1 -  \frac{1}{v} ) \\    - \frac{t}{b}  +  \frac{t}{r}  =  \frac{m( 1 -  \frac{1}{v})  }{(1 -  \frac{1}{v}) }  \\    - \frac{ \frac{t}{b}  +  \frac{t}{r} }{1 - ( \frac{1}{v} ) }  = m

Two ants start at the origin of the rectangular grid shown above where each unit represents an inch. They roam around in differe
weeeeeb [17]
To help clarify the problem, we can plot the two ants on a graph (see attached image). However, we don't need the graph to solve the problem.

Let's first find the distance in their 'x' values:
= |-3| + |4|
The '| |' means that we don't care if it is negative, we just want the positive value.
= |-3| + |4| is the same thing as = 3 + 4
= 7

Now let's find the distance in their 'y' values:
= |5| + |-2|
= 7

From here, since we have the 'x' and 'y' distances, we can create a triangle. The 'x' and 'y' will be our side lengths, and the hypotenuse is then the distance between the two ants. 

In order to find the hypotenuse, we use the Pythagorean theorm: c^{2}=a^{2}+b^{2}

Now we plug and solve:
c^{2}=(7)^{2} + (7)^{2}
c^{2}=98
c= \sqrt{98}

∴The distance between the two ants is \sqrt{98} or 9.899

Hope this helps!

1. what is the x of "5x - 4 = 3x + 8"
maks197457 [2]

Answer:

1. x= -2  2. x= -5  3. x= -11/10

Step-by-step explanation:

1. 5x-3x -4+4=3x-3x+8+4   2x/2=-4/2  x=-2

2. -4x+7x +7-7=-7x+7x-8-7  3x/3=-15/3  x=-5

3. 6x+4x+7-7=-4x+4x-4-7   10x/10=-11/10   x=-11/10

A rectangle measures 12 cm by 4 cm what is the area
Maslowich
In order to find the area you have to multiply length x width 
In this case our length and width are 12cm and 4cm 
So lets multiply those. :P
12 x 4 = 48 cm

Your area = 48cm²

Good Luck! :)
