Si p+ 2p+3p=12, ¿cual es el valor de 5p -1

Nutka1998 [239]

For this case we have the following equation:

$p + 2p + 3p = 12$

To solve we follow the steps below:

We add similar terms from the left side of the equation:

$6p = 12$

We divide between 6 on both sides of the equation:

$p = \frac {12} {6}\\p = 2$

Finally, we have to:

$5p-1 = 5 (2) -1 = 10-1 = 9$

Answer:

$p = 2\\5p-1 = 9$

If it's possible to tell, decide if a and b are positive or negative: a-3>b-3 and b>4

Svetllana [295]

Answer:

a and b are positive

Step-by-step explanation:

We are given that

$a-3>b-3$

$b>4$

We have to find that a and b are positive or negative.

We have

$b>4$

It means b is positive and greater than 4.

$a-3>b-3$

Adding 3 on both sides

$a-3+3>b-3+3$

$a>b>4$

$\implies a>4$

Hence, a is positive and greater than 4.

Therefore, a and b are positive

How to graph 200-25x=y

In-s [12.5K]

Simplifying
y = -25x + 200

Reorder the terms:
y = 200 + -25x

Solving
y = 200 + -25x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 200 + -25x
