Answer 1

1)$45-7=38$- приборов в день собирает вторая бригада;
2)$45+38=83$- прибора в день суммарно собирают первая и вторая бригада;
3)$83*5=415$ - приборов соберут за 5 дней суммарно первая и вторая бригада;
4) $500-415=85$ - приборов останется собрать бригадам после 5 дней;
Ответ: 85 приборов.

Answer 2

Problem Analysis

We are given two teams of workers who need to assemble 500 devices. One team can assemble 45 devices per day, while the other team can assemble 7 devices fewer per day. We need to determine how many devices will remain to be assembled after five days of work.

Solution

Let's calculate the number of devices assembled by each team in five days and then subtract that from the total number of devices.

The first team can assemble 45 devices per day, so in five days, they will assemble 45 * 5 = 225 devices.

The second team can assemble 7 devices fewer per day, so they can assemble 45 - 7 = 38 devices per day. In five days, they will assemble 38 * 5 = 190 devices.

Therefore, the total number of devices assembled by both teams in five days is 225 + 190 = 415 devices.

To find the number of devices remaining to be assembled, we subtract the total number of devices assembled from the initial total of 500 devices:

500 - 415 = 85 devices.

Therefore, after five days of work, there will be 85 devices remaining to be assembled.

Answer

After five days of work, there will be 85 devices remaining to be assembled.
