Mother bought 5 kg of oranges and 4 kg of apples for 32 yuan, 2.6 apples and oranges were several yuan more expensive per kilogram of apples than per kilogram of oranges
If Apple x yuan / kg, then orange (x-2.6) yuan / kg
4x+5(x-2.6)=32
4x+5x-13=32
9x=45
X=5
Apple: 5 yuan / kg
Orange: 5-2.6 = 2.4 yuan / kg
Mother bought 5 kg of orange and 4 kg of apple to share 23 yuan, each kilogram of apple is more expensive than per kilogram of orange 2.6 apples and oranges each several yuan
Let orange x yuan / kg
5x+4(x+2.6)=23
5x+4x+10.4=23
9x=12.6
x＝1.4
Apple: 1.4 + 2.6 = 4 yuan
Orange: 1.4 yuan
Mother bought 5 kg oranges and 7 kg apples, which cost 64.5 yuan in total. It is known that 1.5 yuan is more expensive per kilogram of apples than oranges. How much is the price per kilogram of apples and oranges?
5 × 5. 5 × 5. 5 yuan per kilogram
Mother bought 5 kg of apple and 4 kg of orange, which cost 19.2 yuan. It is known that the price of each kilogram of apple is 0.6 yuan higher than that of orange. What is the unit price of these two kinds of fruits Arithmetic
Apple = (19.2 + 4 × 0.6) × (5 + 4) = 2.4 yuan
Orange = 2.4-0.6 = 1.8 yuan
Mother went to the supermarket to buy 8 kilograms of apples and 12 kilograms of oranges for 48 yuan
48÷[12＋8×﹙1＋1／2﹚]=2
2×﹙1＋1／2﹚＝3
Apples cost 3 yuan per kilogram
It costs 13.6 yuan to buy 2.5kg apples and 2kg oranges. It is known that the price of apples per kilogram is 2.2 yuan higher than that of oranges. The unit price of these two kinds of fruits is each kilogram Ask to use the equation, only set to x, to write out the solution set, the completion of the formula to write the process, do not skip any step!
If the unit price of apple is x yuan / kg, the price of orange is x-2.2 yuan / kg
Then: 2.5x + 2 (x-2.2) = 13.6
2.5x+2x-4.4=13.6
4.5x=18
X=4
X-2.2=1.8
So the price of apple is 4 yuan per kilogram and the price of orange is 1.8 yuan per kilogram
Mother bought 5 kg apples and 3 kg oranges, which cost 36.6 yuan. It is known that the price of apples per kilogram is 0.6 yuan higher than that of oranges Substitution method
From: 5kg Apple + 3kg orange = 36.6 yuan, 1kg Apple = 1kg orange + 0.6yuan
Results: 5 kg orange + 0.6 × 5 = 36.6 yuan
5 kg orange = 33.6 yuan
1 kg orange = 6.72 yuan
1 kg Apple = 6.72 + 0.6 = 7.32 yuan
My mother bought 4 kg of apples and 3 kg of oranges, which cost 31.8 yuan. It is known that the price of apples per kilogram is 0.6 yuan higher than that of oranges. What are the unit prices of apples and oranges? I just forgot about the graduation examination Suppose!
Let x yuan per kilogram of orange and (x + 0.6) yuan per kilogram of apple
4(x+0.6)+3x=31.8
4x+2.4+3x=31.8
7x=29.4
x=4.2
Oranges are 4.2 yuan per kilogram
Apple per kilogram x + 0.6 = 4.2 + 0.6 = 4.8 yuan
Mother bought apples, pears and oranges. The ratio of apples to pears is 3:2. The weight of oranges is 5 / 8 of pears. Can you figure out how many thousands of oranges are less than apples
Apple 12, pear 8, orange 5kg
Apple: pear = 3:2, pear: Orange = 8:5, apple: pear = 3x4:2x4, so Apple: pear: Orange = 12:8:5
12*x+8*x+5*x=25,x=1；
So Apple 12 * 1 kg, pear 8 kg, Orange 5 kg
The fruit store brought in 500 kg of apples, pears and oranges. The mass ratio of apples to pears is 3:2, and the mass of oranges is 5 / 8 of that of pears. How many kilograms are oranges less than pears
The mass ratio of apple to pear is 3:2 = 12:8
If the quality of orange is 5 / 8 of that of pear, then Orange: pear = 5:8
therefore
Apple: pear: Orange = 12:8:5
500/（12+8+5）
=500/25
=25
Oranges are 25 * (8-5) = 25 * 3 = 75kg less than pears
