Answer:
Y IS EVERYTHING THAT IS LESS THAN -3X
Step-by-step explanation:
LOOK AT THE LESS THAN SIGN
2x^-3= 2/x^3
you can't multiple 2x to the power of -3 because is not correct. so you need to change the equation for it to give you an answer

A 12-sided die is rolled. The set of equally likely outcomes is {1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling

1/6 is the probability of rolling a dice and getting less than 3.
Let's make a system of equations to solve for this:
n + q = 84
0.05n + 0.25q = 12.80
where n = nickels and q = quarters.
---
Solve for n in the first equation by subtracting q from both sides.
n = 84 - q
---
Plug n into the second equation.
0.05(84 - q) + 0.25q = 12.80
Distribute 0.05 inside the parentheses.
4.2 - 0.05q + 0.25q = 12.80
Combine like terms.
4.2 + 0.2q = 12.80
Subtract 4.2 from both sides.
0.2q = 8.6
Divide both sides by 0.2.
q = 43
---
Plug 43 for q in the first equation.
n + (43) = 84
Subtract 43 from both sides.
n = 41

There are 41 nickels and 43 quarters in the piggy bank. ✅
