To rent a certain meeting room, a college charges a reservation fee of $ 37 and an additional fee of $ 9.70 per hour. The math c
Svetach [21]
So your equation would be 37 + 9.70x

114 - 37 would get you 77 dollars. Next, you have to find out how many times 9.70 goes into 77. They would be able to rent the room for a total number of 7 hours because that's how many times 9.70 can fit into 77 evenly.

Write equivalent expressions of 18m+42n​
serious [3.7K]

Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!

Please mark as Brainliest! :)
