A batch of cars can carry several tons of goods. If each car carries 3.5 tons, there will be 2 tons more. If each car carries 4 tons, there will be another ton How many tons are there in this shipment?

A batch of cars can carry several tons of goods. If each car carries 3.5 tons, there will be 2 tons more. If each car carries 4 tons, there will be another ton How many tons are there in this shipment?


With X cars
3.5x+2=4x-1
4x-3.5x=2+1
0.5x=3
x=6
The cargo is 3.5x6 + 2 = 23 tons



A batch of goods is transported 15 times more by a truck with a load of 1.5T than by a truck with a load of 4T. If this batch of goods is x, the equation can be formulated


X/1.5=X/4+15
8X=3X+180
5X=180
X=36



How many times does it take a truck to complete? (4 tons) (13.6 tons)


13.6 △ 4 ≈ 4 times
It's going to take four times



There are 15 trucks with a capacity of 2 tons and 4 tons, which can transport 54 tons of yellow sand at one time. How can we reasonably arrange these two trucks with different capacity?


Assuming that these vehicles carry 4 tons, they transport 15 × 4 = 60 tons of Huangsha, 60-54 = 6 tons more. Each vehicle carrying 4 tons carries 4-2 = 2 tons more than that carrying 2 tons. Therefore, there are 6 △ 2 = 3 vehicles carrying 2 tons, and 15-3 = 12 vehicles carrying 4 tons
