Answer:
It’s 10n+12
They put the 2 n’s as an exponent
Step-by-step explanation:
3x+15x = 180
18x = 180
x = 10
10(x+y) + 3x = 180
10x + 10y + 3x = 180
13x + 10y = 180
13(10) + 10y = 180
130 + 10y = 180
10y = 50
y = 5
This question is asking which two numeric values are closer to each other. The smallest gap in between Mercury, and Helium, which is the answer
x = total amount of gumballs
let's start subtracting the balls she's giving away


and we also know that after all that has been subtracted, she's only left with 5, so we can say that

I would say answer choice 1. It’s the only one that makes sense.
I hope this helps! Let me know if you have any questions! Good luck on the rest of your assessment!
