You have 22 dimes and 11 pennies.
120 degrees = 2X60....supplemental total = 180
I would say approximatley 671,385,264 pennies is how much it would take to wrap around the Earth once this answer is really wrong! so heres the right answer two ways: first , if a penny is : 19.05 mm (0.750 in) in Diameter and then earth is 40075.02 km at the middle(Circumference) then it would take 1,577,756,692.9 pennies. Think edge to edge! 40 075.02 kilometer = 1 577 756 692.9 inch second, if you were to lay them standing up back to back, then the Thickness:1.55 mm (0.061 in), so it would take 40,075,020,000 pennies! 40 075.02 kilometer = 40 075 020 000 millimeter so i would estimate that the U.S. made about 125 trillion pennies from 1793 to 2008. so you could do it about twice, however most pennies have a life of 22 days before they end up in the trash.
i will be twice as heavy
Generally, "twice" means double. So, twice X is equal to X plus X. Twice four is eight. simmisinghsaini's answer- But however, doesn't it mean to divide when we have to translate algebraic expressions?
Yes, the diameter of a circle is twice the length of the radius.
You have 22 dimes and 11 pennies.

The X.X1 at the end of the number implies that there could be 1, 11, 21, 31, etc. pennies. Now, we could go through and test the instances. .01 means that there is 1 penny. Therefore, there are 2 dimes to make .31, which does not work. .11 means that there are 11 pennies. Therefore, 22 dimes are required, which make $2.31. This works, so there are 22 dimes.
There are fifteen (15) nickels.
The coins in the store's cash register total $12.50. The cash register contains only nickels, dimes, and quarters. There are twice as many dimes as nickels. There are also twice as many quarters as dimes. How many quarters are in the cash register?
12 quarters 6 dimes
10 dimes 5 quarters
You need to define variables for the different types of coins, write the corresponding equations, then solve them. One equation for each fact. Here are the equations:5N + 10D + 25Q = 1250 D = 2N Q = 2D
Helen has twice as many dimes as nickels and five more quarters than nickels the value of her coins is 4.75 how many dimes does she have?
12 quarters and 6 dimes 2(.25x) + .10x = 3.60 50x + 10x = 360 60x = 360 x = 6
7 quarters 2 dimes 4 nickels
Twelve. Here is how: Using cents rather than decimal dollars: 5n + 10d + 25q = 640 Express the numbers of nickels and quarters in terms of the number of dimes: # of nickels = twice the # of dimes ==> n = 2d # of quarters = 5 less than the # of dimes ==> q = d-5 Substitute for n & q in original equation: 5(2d) + 10d + 25(d-5) = 640 45d - 125 = 640 45d = 765 d = 17 ==> 170 = $1.70 n = 34 ==> 170 = $1.70 q = 12 ==> 300 = $3.00 . . . . . . . . . Total = $6.40
