Answer:
- <u>The farmer bought 170 animals of each species</u>.
Step-by-step explanation:
The translation of the question into English is:
<em>"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?"</em>
<em />
<h2>Solution to the problem</h2>
<u>1. Choose the variable's name and translate the verbal statements into algebraic expressions:</u>
- 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
<u />
<u>2. Solve the equation:</u>
<u>a) Write the equation:</u>

<u>b) Add like terms:</u>

<u>c) Use division property of equalities: divide both sides by 800:</u>

<u>d) Translate the solution into a verbal statement:</u>
Since x represents both the number of calves and the number of cows, the answer is:
- <u>The farmer bought 170 animals of each species</u>.
Answer:
Reflection across the x-axis
Step-by-step explanation:
The points are the same, just opposite of one another. The image looks as if it is a reflection. Think of the x-axis like a puddle and the shape looking into it; try to picture the image seeing its reflection to help.
Answer:
E
Step-by-step explanation:
Distance = 1/3(week -1) + ¾
= 1/3(7) + ¾
= 7/3 + 3/4
= 28/12 + 9/12
= 37/12 miles
4=2/7x
(7)4=2/7x(7)
28=2x
— —
2. 2
14=x
x=14
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.
Hope this helps.
