Let
n-------> the number of nickels
d-------> the number of dimes
we know that
so
-----> equation A
-------> equation B
substitute equation B in equation A
------> equation that can be used to find n
Solve for n
find the value of d
therefore
the answer is
The equation that can be used to find n is
The number of nickels in the collection is
58,593
195,312
292,968
Answer:
292,968
Step-by-step explanation:
Step 1: Use geometric sequence formula
& = the sum of geometric sequence & terms in total (8)
= common ratio (5)
= first term in sequence (3)
Answer:
52
Step-by-step explanation:
We can find the percent of a number by converting the percent to a decimal.
65%=0.65
80(0.65)=52
To find 65% of 80, first write 65% as a decimal by moving the decimal point 2 places to the left and we will get .65. Next, the word "of" means multiply, so we have (.65) (80) = 52.
Therefore, 65% of 80 is 52.
Answer:
It would be:
Step-by-step explanation:
You just subtract the regular numbers so 4.31-2.2 and keep the same scientific notation.
−5.4−(−3.2)−5.4−(−3.2) ?
