Answer:

The farmer bought 170 animals of each species.

Step-by-step explanation:

The translation of the question into English is:

"a farmer bought the same number of calves and cows for 476,000. He/she paid 800 for a calf and 2000 for a cow, how many animals of each species did he/she buy?"

<h2>Solution to the problem</h2>

1. Choose the variable's name and translate the verbal statements into algebraic expressions:

a) number of calves or cows: x

b) He/she paid 800 for a calf: 800x

c) He/she paid 2,000 for a cow: 2000x

d) For 476,00: 800x + 2000x = 476,000 . . . . this is your equation

2. Solve the equation:

a) Write the equation:

$800x+2,000x=476,000$

b) Add like terms:

$2,800x=476,000$

c) Use division property of equalities: divide both sides by 800:

$x=476,000/2,800=170$

d) Translate the solution into a verbal statement:

Since x represents both the number of calves and the number of cows, the answer is:

The farmer bought 170 animals of each species.

Explain how you can check your solution to the equation. Then check the solution.

Hoochie [10]

Answer:

To check if a given value is a solution to an equation:

Evaluate the left-hand side expression at the given value to get a number.

Evaluate the right-hand side expression at the given value to get a number.

See if the numbers match.

Line segments XY and ZY are tangent to circle O. Which kind of triangle must triangle XYZ be?

pychu [463]

When 2 tangents are joined to a circle, the tangents are of equal length so the triangle is isosceles. Then again it is possible for it to be equilateral.

Find the magnitude of the rotational symmetry in a square?

strojnjashka [21]

The magnitude of the rotational symmetry in a square is 4.

The rotational symmetry of a geometric figure is the number of times you can rotate the geometric figure so that it looks exactly the same as the original figure.

So when we roll up a square and stopped when every side is at the bottom, the square is still congruent to its original figure. Since a square has 4 sides, we can roll it up 4 times, every 90 degrees rotation.
