Question

На двух бензозаправочных станциях было 177ц бензина. после того как на одной из них было продано 11,7, ц,а на другой- 7,5 ц, бензина на первой станции осталось в 2 раза больше,чем на второй . Какое количество бензина было на каждой станции первоначальнго??? Помогите пожалуйста! Очень нужно! Можно пожалуйста с полным решением:)

Answer 1

2х+7.5+х+11.7=177

3х=177-7.5-11.7

3х=157.8

х=157.8:3

х=52.6ц бензина-осталось на второй.

2х+11.7=2*52.6+11.7=116.9ц бензина-было на первой станции.

х+7.5=52.6+7.5=60.1ц бензина-было на второй станции.

ОТВЕТ: 116.9ц, 60.1ц

Answer 2

1. 177-11,7-7,5=157,8 - ОСТАЛОСЬ ПОСЛЕ ПРОДАЖИ БЕНЗИНА НА ДВУХ СТАНЦИЯХ

пУСТЬ х центнеров бензина на второй станции, тогда на первой 2х.

х+2х=157,8

3х=157,8

х=52,6 - вторая станция

52,6*2=105,2 - первая станция

 

Answer 3

Problem Analysis

We are given that there were 177 centiliters (ц) of gasoline on two gas stations. After selling 11.7 ц on one station and 7.5 ц on the other station, the amount of gasoline remaining on the first station was twice as much as the amount remaining on the second station. We need to find the initial amount of gasoline on each station.

Solution

Let's assume the initial amount of gasoline on the first station is x ц. Since the amount of gasoline remaining on the first station is twice as much as the amount remaining on the second station, the amount of gasoline remaining on the second station is x/2 ц.

According to the given information, the total amount of gasoline on both stations is 177 ц. Therefore, we can write the following equation:

x + x/2 = 177

To solve this equation, we can multiply both sides by 2 to eliminate the fraction:

2x + x = 354

Combining like terms, we get:

3x = 354

Now, we can solve for x by dividing both sides by 3:

x = 354/3

Evaluating the expression, we find:

x = 118

Therefore, the initial amount of gasoline on the first station was 118 ц. Since the amount remaining on the first station was twice as much as the amount remaining on the second station, the amount remaining on the second station is 118/2 = 59 ц.

Answer

The initial amount of gasoline on the first station was 118 ц, and the initial amount of gasoline on the second station was 59 ц.
