At this time, the number of people needed to be transferred from workshop a to workshop B is 18?

At this time, the number of people needed to be transferred from workshop a to workshop B is 18?

Suppose there are x people in workshop B, the equation is: 14 (x + 18) = x-18 & nbsp; & nbsp; & nbsp; 14x + 92 = x-18, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 34x = 22.5, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 30 A: there were 30 people in workshop B
The number of people in workshop a and workshop B used to be equal. Due to the need of work, 18 people were transferred from workshop a to workshop B. at this time, the number of people in workshop a is just one fourth of that in workshop B. how many people are there in workshop B now?
After the transfer of 18 people from workshop a to workshop B, the number of people in workshop B is more than that in workshop a: 18 × 2 = 36 (people) the number of people in workshop a is one fourth of that in workshop B, that is, the number of people in workshop B is 1-1 / 4 = 3 / 4 more than that in workshop a. the number of people in workshop B is 36 △ 3 / 4 = 48 (people). The original number of people in workshop B is 48-18 = 30 (people)
In a factory, the ratio of the number of people in workshop a and workshop B is 4:3. Due to the need of work, 10 people are transferred from workshop a to workshop B. at this time, the number of people in workshop B accounts for 24% of the number of people in the two workshops. How many people are there in workshop B now?
A: there are 70 people in workshop B now
The original number of team B is 37 times that of team A. now 30 people are sent from team a to team B. the ratio of team B to team a is 2:3. How many people are there in team a and team B?
Total number: 30 △ 73 + 7-32 + 3 = 30 △ 710-35 = 30 △ 110 = 300 (people) team a: 300 × 73 + 7 = 300 × 710 = 210 (people) team B: 300-210 = 90 (people) a: team a: 210 people, team B: 90 people
The original number of team B is 3 / 7 of that of team A. now the number of team B is 2 / 3 of that of team a when 30 people are sent from team a to team 1
All: 30 / [2 / (2 + 3) - 3 / (3 + 7)] = 300 (people)
A: 300 * [7 / (3 + 7)] = 210 (persons)
B: 300-210 = 90 (person)
210 in team a and 90 in team B.
Yes, there is more than one answer
The two trains leave from both sides at the same time. Car a travels 55 kilometers per hour, 10% faster than car B. after three hours, the two trains travel the whole distance
How long is the railway between Party A and Party B?
1260 55 / 110% = 50 (b speed) 55 + 50 = 105 105 * 3 = 315 (running distance) 315 / 25% = 1260
Three cars can transport 165 tons of goods per day. If two more cars are added, how many tons of goods can be transported per day? (by proportion)
165 / 3 = the traffic volume of each vehicle. If 2 vehicles are added, 5 vehicles will be transported, 165 / 3 * 5 vehicles can be transported every day
There are 45 people in team a and 75 people in team B. how many people in team a should be transferred to team B, and the number of people in team B is three times that of team a?
There should be detailed expressions
(45 + 75) / (3 + 1) = 30 (person)
45-30 = 15 (person)
A: team a should have 15 people like team B, and team B has three times as many as team a
On the map with a scale of 1:6000000, the distance between the two places is 5cm. A and B leave from both places at the same time and meet in three hours. The speed of a and B is known
The ratio is 2:3. How many kilometers do they travel?
S actual distance between the two places = 0.05m * 6000000 = 30wm = 300km
Line a 300 * 2 / 5 = 120km
B: 300 * 3 / 5 = 180km
A 1200 km
B 1800 km.
A 120 km, B 180 km
6000000 cm = 60 km
60 × 5 = 300 km
A = 2 + 300 km
Line B: 300-120 = 180 km
The actual distance between the two places is 0.05m * 6000000 = 30wm = 300km
300 * 2 / 5 of a = 120km
B: 300 * 3 / 5 = 180km
Glad to answer for you!

S actual distance between the two places = 0.05m * 6000000 = 30wm = 300km
Line a 300 * 2 / 5 = 120km
B: 300 * 3 / 5 = 180km
Solution:
On a map with a scale of 1:6000000, the distance between the two places is 5cm, and the distance between the two places is 5cm
6 / (1:6000000) = 5 * 6000000 = 30000000 cm = 300km
A and B leave each other at the same time and meet three hours later. So the combined distance is 300 kilometers
According to the distance and time, the speed can be calculated, which is the sum of the two speeds
300 / 3 = 100 km / h
That is, the sum of a and B speed is 100 thousand
Solution:
On a map with a scale of 1:6000000, the distance between the two places is 5cm, and the distance between the two places is 5cm
6 / (1:6000000) = 5 * 6000000 = 30000000 cm = 300km

According to the distance and time, the speed can be calculated, which is the sum of the two speeds
300 / 3 = 100 km / h
That is, the sum of speed is 100 km / h
The speed of a is 100 * 2 / (2 + 3) = 40 km / h
B's speed is 100 * 3 / (2 + 3) = 60 km / h
A: put it away
S actual distance between the two places = 0.05m * 6000000 = 30wm = 300km
Line a 300 * 2 / 5 = 120km
B: 300 * 3 / 5 = 180km
If you don't understand, you can ask
Welcome to adopt
A and B start from ab at the same time and travel in opposite directions. A travels 45 kilometers per hour and B 55 kilometers per hour. If a adds 15 kilometers per hour and B adds 5 kilometers per hour, the meeting time will be one fourth of an hour earlier. How many kilometers is the distance between ab and B?
It's OK to have a formula or an equation~
Let AB distance be x km
x/(45+55)-x/(45+15+55+5)=1/4
x/100-x/120=1/4
x*(1/100-1/120)=1/4
x*1/600=1/4
x=1/4*600
x=150
A: the distance of AB is 150 kilometers
