Answer:
14
Step-by-step explanation:
Think how many times does 6 go into 84.
you can divide 84 into 6 which is 14.
Or you can think what times 6 equals 84.
Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
Answer:
three occupies the hundredths place (it is 3/100 of a whole number)
I'm having the same troubles with this type of geometry sort of.
Well, if you need the number (0.000006) to be more than 1 and less than ten, you need to move the decimal point. So, 0.000006-----> 6.0 and then, how places did you move the decimal to get 6.0 instead of 0.000006? Well, the answer is 6 so if you multiply 6.0*10 to the -6
The solution is 0.6*10 the the -6 power
Do you need anymore questions answered?
