The answer is simple.
First, you must look what is the least among the list. In this case, it is 16x.
Then get the factors of 16x and they are (4,4) , (8,2) and (16,1).
Since you can't then divide it to 36.
Since you can't divide 36 by 16 and 8. You must eliminate them from the list of GCF.
2 and 4 are possible but 4 is the greatest Common Factor which can be divided to both 16 and 36.
<span>N + D = 55 coins (1) (N stands for nickels,
5N + 10D = 390 cents (2) D stands for dimes)
Simplify (2) by canceling the factor 5 in both sides:
N + 2D = 78 (3)
Subtract eq(1) from eq(3). You will get
D = 78 - 55 = 23.
Answer. 23 dimes and 55-23 = 32 nickels.
Check. 23*10 + 32*5 = 390 cents</span>
Answer:
16
Step-by-step explanation:
x+y=30 solve for x x=30-y
substitute x with 30-y and solve
11.25x+22.4y=515.9
11.25(30-y)+22.4y=515.9
337.5+11.15y=515.9
11.15y=178.4
y=16
since we're solving for just large candles it's 16
if need small cangle number 30-16=14
