Using a system of equations, the amounts in grams of each mix that should be used are given as follows:

  • A: 60 grams.
  • B: 50 grams.
  • C: 40 grams.

<h3>What is a system of equations?</h3>

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the variables are given as follows:

  • Variable a: number of grams of substance A.
  • Variable b: number of grams of substance B.
  • Variable c: number of grams of substance C.

The mix has 23g of protein, hence, from the table:

0.2a + 0.1b + 0.15c = 23.

The mix has 6.2g of fat, hence:

0.02a + 0.06b + 0.05c = 6.2.

The mix has 16g of moisture, hence:

0.15a + 0.1b + 0.05c = 16.

Hence the system is given by:

  • 0.2a + 0.1b + 0.15c = 23.
  • 0.02a + 0.06b + 0.05c = 6.2.
  • 0.15a + 0.1b + 0.05c = 16.

Using a calculator, the solution for the system is given as follows:

a = 60, b = 50, c = 40.

Which are the amounts in grams of each substance.

<h3>What is the missing information?</h3>

The table containing the compositions of the mix is missing, and is given at the end of the answer.

A paragraph proof is a two-column proof in sentence form.

Step-by-step explanation:

  • In a paragraph proof, statements and their justifications are written in sentences in a logical order.
  • A two-column proof consists of a list statements and the reasons the statements are true.
  • A paragraph proof is a two-column proof in sentence form.

A paragraph proof is only a two-column proof written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.

A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column

No, it is not possible for Eric to have spent 35 minutes playing basketball if he plays for a total of exactly 95

<h3>How to form a linear equation</h3>

Let the time taken to play basketball be "x"

Let the time taken to play volleyball be "y"

According to the information given, Eric plays basketball and volleyball for a total of 95 minutes every day, then;

x + y = 95

If he plays basketball for 25 minutes long, then;

x = 25

The pair of linear equations that represents the statement are:

x  + y = 95
x = 25

The time it takes Eric to play volleyball every day is expressed as:

y = 95 - x

y = 95 - 25

y = 70 minutes

No, it is not possible for Eric to have spent 35 minutes playing basketball if he plays for a total of exactly 95
