Becky has 9 bags of coins. Some of the bags contain 8 gold coins, and the rest contain 6

fredd [130]

Answer:

4 bags of gold coins and 6 bags of gold coins

Step-by-step explanation:

So, Becky has 9 bags of coins

This is basically a "trial and error" equation.

Now, she has 4 bags of 8 gold coins

8×4= 32

So she has 32 gold coins

Now, she has 5 bags of 6 silver coins

5×6=30

So she has 30 silver coins.

So we add these,

30+32= 62

HOPE THIS HELPS!!!

Please solve the inequality: -15< or equal to 5(3p-2) and is < and equal to 20

Levart [38]

It has been awhile since I worked with in qualities but I got the answer, -1/3 < or equal to p < or equal to 2. I multiplied the 5 in the middle of the equation with what's in parentheses to get 15p - 10, then I added 10 to both outer sides of the equation and got -5 < or equal to 15p < or equal to 30. Then lastly I divided 15 by -5 and 30! I hope that's right.. I'm sorry if it isn't!
