Question

Чтобы сделать казеиновый клей,берут 11 частей воды,5 частей нашатырного спирта и 4 части казеина (по массе).Сколько получится казеинового клея,если на него будет израсходовано нашатырного спирта на 60 г меньше,чем воды? надо решить уравнением и с условием,в ответе должно получится ответ-200,но я незнаю как решить.помогите пожалуйста..

Answer 1

Х - это одна часть
11х -вода, 5х - н.спирт, 4х - казеин
11х-5х=60
6х=60
х=60:6
х=10
10грамм - одна часть, значит 11×10=110 (г) - вода
                                              5×10=50 (г) - н.спирт
                                              4×10=40 (г) - казеин
110+50+40=200(г) - клея
Ответ : 200 грамм

Answer 2

Solving the Equation for Making Casein Glue

To solve the problem, we can use the given information to set up an equation and solve for the amount of casein glue produced.

Let's denote: - x as the amount of water used - y as the amount of denatured alcohol (naшатырный спирт) used - z as the amount of casein used

Given: - 11 parts water - 5 parts denatured alcohol - 4 parts casein

We are also given the condition that the denatured alcohol used is 60g less than the water used.

The equation representing the given information is: 11x + 5y + 4z = Total amount of casein glue And the condition is: y = x - 60

We need to solve for the total amount of casein glue, which should result in -200.

Let's proceed with solving the equation and the condition to find the total amount of casein glue.

Solving the Equation and Condition

First, we can express y in terms of x using the given condition: y = x - 60

Substitute the expression for y into the equation: 11x + 5(x - 60) + 4z = Total amount of casein glue 11x + 5x - 300 + 4z = Total amount of casein glue 16x - 300 + 4z = Total amount of casein glue

We also know that the total amount of casein glue should result in -200: 16x - 300 + 4z = -200

Now, we need to solve for x and z to find the total amount of casein glue.

Finding the Total Amount of Casein Glue

To solve for the total amount of casein glue, we need to find the values of x and z that satisfy the equation: 16x - 300 + 4z = -200

By solving for x and z, we can find the total amount of casein glue produced.

I hope this helps! Let's continue with the calculations to find the total amount of casein glue.
