The answer you want is x = -30

Answer: x = 30

Explanation:

This equation is almost solved, it is on the last part of the equation.

First thing you must always do is write the equation as you see it, making sure you don’t miss any plus or minus signs:

-1/5x = 6

Next, you must do the math. All that you must do is divide the the side that doesn’t have x with the side that does:

6 ÷ -1/5x

Change the fraction into decimal ( that is optional, but it makes that math easier):

6 ÷ 0.2x = 30x

Your answer is 30x

Hope this helps! :)

The football coach is overseeing the installation of new goal posts on the football field. He is wondering if the goal posts are
Westkost [7]

Answer:

Correct option is D. No, since the ratios of the corresponding sides are not proportional.

Step-by-step explanation:

Please refer to the attached figure

Let height of coach represents by AB = 6 feet

And shadow of coach represents by BC = 4 feet

Let height of goal post represents by DE = x feet

And Shadow of goal post represents by EF = 12 feet.

Since measurement of shadows are at same time. therefore  ratio of height of coach and height of goal post  must be same as ratio of shadow of coach and shadow of goal post.

⇒ 6/x = 4/12

⇒x = 72/4 = 18 feet

So goal post is not at regular height , since expected height is 20 feet while actual height is 18 feet . And if we consider value of x as 20 feet instead of 18 feet , ratio of corresponding sides will not match.

Hence correct answer is D. No, since the ratios of the corresponding sides are not proportional.

*PLEASE ANSWER* What is the perimeter of the triangle below?
brilliants [131]

Answer:

16.7 Units

Step-by-step explanation:

To find the length of r, you set up the equation as sin(45)= 4.9/r. Then you get r by itself changing it to r = 4.9/sin(45). Then you can find that r = 6.9. Since this is an isosceles triangle, n^1 has to be equal to 4.9. Then you add all the side lengths together. 4.9 + 4.9 + 6.9 = 16.7 units
