In typesetting, a planned to do 7 / 12, but he finished it first, and then arranged 24 pages for B. at this time, the ratio of pages arranged by them was 5:3. How many pages were there in this typesetting The answer should be complete and clear!
A is finished
5 ÷ (5 + 3) = 5 / 8
What's wrong with this typesetting
24 (5 / 8-7 / 12) = 576 pages
There are 100 workers in a workshop, each of whom processes 18 bolts or 24 nuts per day on average
Linear equation of one variable
(1) there are 100 workers in a workshop, each of whom processes 18 bolts or 24 nuts per day on average. In order to match the bolts and nuts processed every day (one bolt needs two nuts), how to allocate the workers who process bolts and nuts?
(2) there are 54 workers in the processing workshop of a garment factory, each of whom can process 8 coats or 10 pants per day. How to allocate the number of workers to make the daily production of coats and pants match?
(3) in a basketball game, Kobayashi scored 28 points (excluding free throw). It is known that he has 4 more two-point shots than three-point shots. How many two-point shots did he hit? How many three-point shots?
(4) an engineering team arranges 120 labors to build the reservoir every day, and each laborer can dig 5 cubic meters of soil or transport 3 cubic meters of soil every day. In order to transport the excavated soil away in time, how to arrange the labors for digging and transporting soil?
1) Processing bolt x person
18x*2=(100-x)*24 x=40
40 bolt, 60 nut
2) Processing x people
8x=10*(54-x) x=30
30 top and 24 pants
3) Two points x
2x+3*(x-4)=28 x=8
Eight two, four three
4) Earth digger
5x=3*(120-x) x=45
Soil excavation 45 soil transportation 75
There are 100 workers in a workshop, each processing 18 bolts or 27 nuts per day
The bolts processed every day should be matched with nuts (one bolt with two nuts)
How to assign workers to process bolts and nuts
If the number of processing bolt is (100 - χ), the number of processing nut is (100 - χ)
18χ=2*27(100-χ)
χ=75
Answer: the number of people processing bolts is 75, and the number of people processing nuts is 25
There are 27 workers in a workshop, each producing 12 bolts or 18 nuts per day
How many workers should be assigned to produce bolts and how many workers should produce nuts so that the bolts and nuts produced on the same day can match each other? (it is known that each bolt should be equipped with two nuts)
Solving linear equation with one variable
Equipped with X workers to produce nuts, (27-x) workers to produce bolts
18x=(27-x)*2*12
x=15.4
Is the title wrong?
There are 21 workers in total, that is, 12 workers produce nuts
