Xiao Ming has saved 87.5 yuan, which is 1 yuan and 50 Jiao coins. The number of one yuan coins is three times that of the pentagons. How many are there in each

Pentagonal = 87.5 × (2 × 3 + 1) ÷ 0.5 = 25 pieces
1 yuan = 25 × 3 = 75 pieces

There are some quarters and dimes, which are worth 27.9 yuan. The number of Dimes is four times that of fifty cents. How many coins are there? How many dimes are there? I'll take it in a minute

If there are x quarters, the number of Dimes is 4x (the number of Dimes is 4 times of the number of Dimes), so 4x + 5x = 279. (x coins with 5 cents are 5x coins, and 4x dimes with dimes are 4x Jiao coins, which is 9x Jiao coins, because the total value is 27.9 yuan, i.e. 279 cents), x = 31, 4x = 124, so there are 31 coins with 5 cents and 124 coins with 1 jiao

There are some quarters and dimes worth 27.9 yuan. The dime is four times as many as the number of fifty cents. How many formulas are there for the coin

If there are x quarters, the number of Dimes is 4x (the number of Dimes is 4 times of the number of Dimes), so 4x + 5x = 279. (x coins with 5 cents are 5x coins, and 4x dimes with dimes are 4x Jiao coins, which is 9x Jiao coins, because the total value is 27.9 yuan, i.e. 279 cents), x = 31, 4x = 124, so there are 31 coins with 5 cents and 124 coins with 1 jiao

There are 87.5 yuan in the bank, which are 1 yuan and 5 jiao coins. If the number of 1 yuan is 3 times that of 5 jiao, how many 1 yuan and 5 jiao coins are there

Method 1
If there are x coins with 50 cents, there are 3x coins with 1 yuan
3x*1+x*0.5=87.5
x=25
3x=3*25=75
There are 25 dimes and 75 yuan coins
Method 2
One dollar coin is equivalent to two quarters
Then there are five dimes
87.5 / (0.5 + 2 * 3 * 0.5) = 25 (PCs.)
There are 1 yuan coins
25 * 3 = 75

There are 87.5 yuan in the piggy bank. There are 1 yuan and 5 jiao coins. If the number of 1 yuan coins is three times that of 5 jiao coins, how many 1 yuan and 5 jiao coins are there respectively?

35 of one yuan
105 in the Pentagon

There are 87.5 yuan in Xiaoming's piggy bank, which are 1 yuan and 5 jiao coins. If the number of 1 yuan coins is 3 times that of 5 jiao, how many coins are 1 yuan and 5 jiao

0.5x+3x=87.5
3.5x=87.5
x=25
3x25 = 75
A: there are 25 dimes and 75 1 yuan coins

There are 87.5 yuan in Xiaoming's piggy bank, which are 1 yuan and 5 jiao coins. If the number of 1 yuan coins is 3 times that of 5 jiao coins How many coins are there for 1 yuan and 5 jiao Let 5 corners be x pieces

If there are x pentagons, then 3x ones are unitary
5 x + 1 * 3x = 87. 5
The solution is x = 25
So there are 3x = 3 * 25 = 75 yuan, and 25 pentagonal ones

Xiao Ming's piggy bank has 87.5 yuan in total, which are both one yuan and fifty cents. If the number of 1 yuan coins is three times that of the five jiao coins, how many are there in each

Let's say there are x pieces in 5 corners and 3 x pieces in 1 yuan
0.5x+3x=87.5
3.5x=87.5
x=25
1 yuan: 25 × 3 = 75 pieces

There are several 1 yuan coins and 5 jiao coins, which are worth 675 cents. If the number of 1 yuan coins and 5 jiao coins is exchanged, the total amount is 600 Jiao. How many coins are there in the original 50 cents? Using the hypothesis method

(675 + 600) / (10 + 5) = 85
Assuming that 85 pieces are all 1 yuan, there are 85 × 10 = 850 angles
More than the actual: 850-675 = 175 angle
If you take a 5-jiao as a yuan, you will calculate more: 10-5 = 5 jiao
There are 175 △ 5 = 35 pieces in 5 corners
1 yuan: 85-35 = 50 pieces

There are 1 yuan coins and 5 jiao coins. How many dimes are worth 675 cents in total. If the number of 1 yuan coins and 5 jiao coins is exchanged, the total is 600 cents. How much is the original 50 cents

1 yuan = 10 Jiao
(675 + 600) × (10 + 5) = 85 (pieces)
(675-600) × (10-5) = 15 (pieces)
The original 5 horns are: (85-15) × 2 = 35 (pieces)
