Answer:

5v + 3 = 5v – 5

Step-by-step explanation:

In an equation, if the variable is cancelled and we get a statement that is false, the equation has no solution.

5v+3 = 5v-5

Since we have a variable on both sides, our first step would be to subtract 5v from each side:

5v+3-5v = 5v-5-5v

3 = -5

There is never a time that 3 is equal to -5; thus there is no solution.

The first one:
5v + 3 = 5v - 5
Subtract 5v from both sides ->
3 = -5
This isn't true so that means there are no solutions...

A boy purchased (bought) a party-length sandwich 51 in. long. He wants to cut it into three pieces so that the middle piece is

shepuryov [24]

Answer:

Step-by-step explanation:

we have a 51 in sandwich

let a piece be x

we have x= shorter piece

another piece is x+6

another piece (x+6)-9=x-3

x+x+6+x-3=51

3x=51-3

3x=48

x=48/3=16

x=16, longer piece is 16+6=22, shorter piece =10

In the diagram, p is the centroid of abc and pd = 3. find bd.

Anna35 [415]

We know that
if P is the centroid of triangle ABC
so
PD=(1/3)*BD
BD=3*PD-----> BD=3*3-----> BD=9 units

the answer is
BD=9 units

Find a in the figure below and place the value in the empty box

AleksAgata [21]

Answer:

a = 12m

Step-by-step explanation:

In order to solve this problem we will need to know the Pythagoras theorem that states that in a right angled triangle the square of the hypotenuse (the side opposite to the right angel) is equal to the sum of the squares of the other two sides. This theorem can be written as an equation....

$c^{2} = a^{2} + b^{2}$
