Answer:
Answer: 4.8 ounces
Step-by-step explanation:
In total there are 12 ounces. If she drinks 3/5 of 12 you multiply 3/5 by 12.
3/5 * 12 would be equal to 3/5 * 12/1 which is 36/5. You have found how much she has drank. 36/5 is also equal to 7.2 ounces. Subtract 7.2 form 12 and you get 4.8 ounces.

Answer:
See below
Step-by-step explanation:
Angle A is congruent to Angle C because of alternative interior angles
ABE is congruent to CDE because of ASA
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. ✅
