Answer:

900

Step-by-step explanation:

You would substitute n for 3 so it would be 60x3=180 then multiply that by 2 = 360. Then take the 180 and multiply that by -3 to get -540. Finally do 360 - (-540) into a calculator to get 900.

Determine whether the given length can be side lengths of a right triangle. 12m, 60m, 61m
Ne4ueva [31]

Answer:

No

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.

The longest side = 61, thus

61² = 3721

12² + 60² = 144 + 3600 = 3744 ≠ 3721

Thus these sides do not form a right triangle.

ben earned 45 dollars mowing lawns. he worked 3.2 hours on monday and 4.3 hours on tuesday. how much did he earn per hour?
dlinn [17]

Answer:

6 dollars per hour

Step-by-step explanation:

We can set up and solve an equation to answer this question. For this problem, let x stand for the amount he earned per hour. The equation that represents this situation is 3.2x + 4.3x = 45. The first term represents monday and the second represents tuesday. When these add up they should equal 45 because that is the total amount he made. To find his pay per hour, solve for x.

First, combine the like terms

  • 7.5x=45

Next, divide both sides by 7.5

  • x=6
