U have a 90% chance of picking an orange marble, 10% of picking a different color
For this case, the first thing we must do is define variables:
x = number of quarters
y = number of dimes
We now write the system of equations:
x + y = 28
0.25x + 0.10y = 4.05
Solving the system of equations we have:
x = 8.33
y = 19.66
Rounding:
x = 8
y = 20

Answer:
99
Step-by-step explanation:
8 + 7(4^2 - 3)
Solve what’s in the parentheses first, starting with 4^2:
8 + 7(16 - 3)
Continue solving what’s in the parentheses:
8 + 7(13)
Considering the order of operations, multiply 7(13) before adding 8:
8 + 91 = 99
