Afarmer sold 20 cows at $300 each. all of the money was spent to buy 15 bulls. how much did each bull cost?

Step-by-step explanation:

In this question, we're trying to find how much each bull cost.

We know that:

With the information above, we can solve the question.

To find how much the farmer made from the cows, we would multiply 20 by 300

The farmer made $6,000 from the cows.

We know that the farmer used all the money to buy 15 bulls.

We would divide 6000 by 15 to find the cost for each bull.

When you divide, you should get 400.

This means that each bull cost $400 each.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
