9. Elijah had three sets of five marbles. He gave 6 marbles to his sister and had three sets of three marbles left. What does th
Licemer1 [7]

Answer:

(3x5) -6 = 3x3

Step-by-step explanation:

So we know that elijah starts with 3 sets of 5 marbles each.

This can be thought of as 3 x each set, or 3 x 5.

Elijah then gives away 6 marbles from this set, or in other words subtracts 6.

How can this be put into a equation, however?

We know that we are taking 3x5, and subtracting it by 6. However it isnt as simple as 3x5-6.

It would have to be (3x5)-6, since your sets are a total of 15, or 3x5. This total is being subtracted to by 6.

This can be written as:

(3x5)-6

The only equation in your list that looks like this would be the third one, where:

(3x5)-6 = 3x3

So this would be your answer!

Hope this helps! :3

Thepotemich [5.8K]
E. 8x+7(325)=15(325)

It would include the 8 hrs. of x miles per hour and the 7 hrs. of 325 miles per hour, giving the total miles. Then, as you eliminate, you can find out what (x) is.
