Question

Тракторная бригада должна была по плану вспахивать ежедневно 112 га.Перевыполняя план на 8 га в день, бригада уже за день до срока закончила пахоту. Сколько гектаров нужно было вспахать бригаде? Помогите плизз)

Answer 1

х дней - заданное время

112+8=120 (га

120(х-1)=112х

120х-120=112х

8х=120

х=15 (дней)

112*15=1680 (га)

Answer 2

Calculation of the Area to be Plowed

To determine the number of hectares that the tractor brigade needed to plow, we can use the information provided. The brigade was originally planned to plow 112 hectares in total. However, they exceeded the plan by plowing an additional 8 hectares each day. As a result, they finished plowing one day ahead of schedule.

To calculate the total area that needed to be plowed, we can subtract the extra hectares plowed each day from the total area planned. Since the brigade finished one day ahead of schedule, we need to subtract 8 hectares from the total area.

Let's calculate the total area that needed to be plowed:

Total area planned: 112 hectares Extra hectares plowed each day: 8 hectares Days ahead of schedule: 1 day

Calculation: Total area = Total area planned - (Extra hectares plowed each day x Days ahead of schedule)

Total area = 112 hectares - (8 hectares x 1 day) Total area = 112 hectares - 8 hectares Total area = 104 hectares

Therefore, the tractor brigade needed to plow 104 hectares in total.

Answer 3

Calculation of the Area to be Plowed

To determine the number of hectares that the tractor brigade needed to plow, we can use the information provided. The brigade was originally planned to plow 112 hectares in total. However, they exceeded the plan by plowing an additional 8 hectares each day. As a result, they finished plowing one day ahead of schedule.

To calculate the area that needed to be plowed, we can subtract the extra hectares plowed each day from the total area planned. Since they finished one day ahead of schedule, we need to subtract 8 hectares from the total area.

Let's calculate the area that needed to be plowed by the brigade:

Total area planned: 112 hectares Extra hectares plowed each day: 8 hectares Days completed ahead of schedule: 1 day

Calculation:

Total area to be plowed = Total area planned - (Extra hectares plowed each day * Days completed ahead of schedule)

Total area to be plowed = 112 hectares - (8 hectares * 1 day)

Total area to be plowed = 112 hectares - 8 hectares

Total area to be plowed = 104 hectares

Therefore, the tractor brigade needed to plow 104 hectares in total.
