7p − p = 18 2) −5n − 4n = −9

Savatey [412]

Answer:

<h3> $\boxed{ \bold{ \sf{ \boxed{ p = 3}}}}$ </h3>

$\boxed{ \bold{ \sf{ \boxed{n = 1}}}}$

Step-by-step explanation:

1. $\sf{7p - p = 18}$

Collect like terms

⇒ $\sf{6p = 18}$

Divide both sides of the equation by 6

⇒ $\sf{ \frac{6p}{6} = \frac{18}{6} }$

Calculate

⇒ $\sf{p = 3}$

2. $\sf{ - 5n - 4n = - 9}$

Collect like terms

⇒ $\sf{ - 9n = - 9}$

Divide both sides of the equation by -9

⇒ $\sf{ \frac{ - 9n}{ - 9} = \frac{ - 9}{ - 9} }$

Calculate

⇒ $\sf{n = 1}$

Hope I helped!

The ratio of coins to notes in a bag is 3 to 8. If there are a total of 24 coins then how many notes are there?

BaLLatris [955]

Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag
