Answer:
Correct answer: Nickels x = 11 and pennies y = 9
Step-by-step explanation:
We will first define the variables in the system:
Let be nickels x and pennies y
We will form a system to solve this problem:
5 x + 1 y = 64
x + y = 20/ · (-1)
we will first multiply the second equation by -1 and add it by the first and get:
4 x = 44 ⇒ x = 44 / 4 = 11 nickels
x = 11 nickels
from the other we get y
y = 20 - x = 20 - 11 = 9 pennies
y = 9 pennies

Answer:
1728
Step-by-step explanation:
You could write it like this
5.4 * 10^5 * 3.2 * 10^-3
You could do this by multiplying the numbers first
5.4 * 3.2 = 17.28
Now work with the powers of 10
10^5 * 10^-3 = 10^(5 - 3) = 10^2
10^2 = 100
So the answer is 17.28 * 100 = 1728
Divide the two numbers
1088 divided by 32 = 34
