Question

1)Верно ли неравенство (а+253)*7<(9864-а):4 при а=124?2)В четыре стакана помещается столько же молока, сколько и в банку. В стакан и банку помещается 1кг 200г молока. Сколько граммов молока помещается в стакан. помогите!Пожалуйста, можете не все решить но хоть за какуето помощь сспасибО!

Answer 1

1) (124+253)*7<(9864-124):4
377*7<9740:4
2639<2426 - неверно

2) 1кг200г=1200г
Хг - в одном стакане
4х - в банке
х+4х=1200
5х=1200
х=240 г - в одном стакане

Answer 2

1)Верно ли неравенство (а+253)*7<(9864-а):4 при а=124?
При а=124; (124+253)*7=2639;
При а=124;(9864-124):4=2435.
Сравниваем: 2639 и 2435,2639 то есть (а+253)*7 будет больше...
Значит,равенство не верное.
Как-то так))

Answer 3

1) To determine if the inequality (a + 253) * 7 < (9864 - a) / 4 is true when a = 124, we can substitute the value of a into the inequality and evaluate both sides.

Substituting a = 124 into the inequality, we get:

(124 + 253) * 7 < (9864 - 124) / 4

Simplifying both sides of the inequality:

377 * 7 < 9740 / 4

2639 < 2435

The inequality 2639 < 2435 is false. Therefore, the original inequality (a + 253) * 7 < (9864 - a) / 4 is also false when a = 124.

2) Let's solve the problem about the milk together. We are given that the total amount of milk that can be accommodated in four glasses and one jar is 1 kg 200 g.

Let's assume that the amount of milk in the jar is x grams. Since the same amount of milk can be accommodated in each glass and the jar, the amount of milk in each glass is also x grams.

So, the total amount of milk in the glasses is 4x grams.

According to the given information, the total amount of milk in the glasses and the jar is 1 kg 200 g, which is equal to 1200 grams.

Therefore, we can write the equation:

4x + x = 1200

Simplifying the equation:

5x = 1200

Dividing both sides of the equation by 5:

x = 240

Therefore, the amount of milk that can be accommodated in each glass is 240 grams.

I hope this helps! Let me know if you have any further questions.
