Answer:
I believe it is C because i heard of that one before
B I would guess it’s kinda hard to understand
Two say to the sixth power is 420 which equals 12 which would take 420÷12 which is 2002 10 200 to 6 power is 420÷64 = 36
Let x be the number of nickels and y be the number of quarters.
Then, x + y = 42 --- (1)
It is given that total value = 4.90.
Therefore, 0.05x + 0.25y = 4.9 --- (2)
Multiply (1) by 0.25
0.25x + 0.25y = 10.5 --- (3)
Now, subtract (2) from (3), we get,
0.2x = 5.6
Divide both sides by 0.2.
x = 28
x + y = 42
y = 42 - x
= 42 - 28
= 14
Hence, Mary has 28 nickels and 14 quarters in total.
Answer:
m = -2
Step-by-step explanation:
Since 10 is smaller than 12, we have to subtract to get a negative number.
10 - 12 = -2
