1 A car wants to transport 200 tons of goods, each time a ton is transported, it is transported 5

1)200-5*a (2)10*m (3)8x+ 。1) Sold watermelon (2)A-5B (3)210-5*40=10 (kg).

The answer is in order: 200-5a 10m 8x 16 The quality of watermelon sold in 5 days A-5b is substituted to get 210-5*40=10 (kg).

1.Elementary school topics, 200-a 50

2. 10×m

3.8 times +

4.(1) How much was sold.

2） a-5×b

3) 210-5×40=10(kg)

(1) A car wants to transport 200 tons of goods, each time a ton is transported, it is transported 5 times, and the remaining tons are not transported.

200-5a

2) A fountain pen is 10 yuan, and my mother bought M branches, and it costs () yuan in total.

10m3)The sum of x times of 8 is expressed by the formula of the letter ().

X+ Fresh Fruit Store brought in a kilogram of watermelon and sold it for 5 days, selling B kilograms every day. (1) 5b represents ( ) 2) The number of kilograms of remaining watermelons is expressed by the formula (). 3) It is known that a=210, b=40.

Use the above formula to find how many kilograms of watermelon are left.

1) Watermelons sold in 5 days.

2）a-5b

3) 210-5 40 = 10 kg.

2 tons = 2000 kg, 2000 5 = 400 (kg old);

A: This car can carry 400 kilograms of Lashan cargo wheels each time

So the answer is: 400

There were tons of cargo, which were transported 3 times by a truck with a load of B tons, and there were (A-3B) tons of cargo left.

According to the inscription, it is known that a truck has a load of 6 tons, and if it is used to transport a batch of 200 tons of goods and it has been transported 18 times, it is realistic to find out how many tons of goods are left undelivered. So, the detailed steps are as follows:

92 tons. Therefore, after 18 shipments, there are still 92 tons of goods left to be delivered.

1) (a-b) 4 tons.

2) When a=50, b=8.

a-b）÷4

Tons) Answer: The formula that expresses the average number of tons transported each time is (a-b) 4;When a = 50 and a lot of congratulations b = 8, each time the ton is transported

So the answer is: reed stool (a-b) 4, accompany the bend brigade.

The cargo totaled tonnes. After two cars were transported three times, there were tons left.
