If you are trying to find the unit rate, you can find it by dividing. you wanna find out how many miles in 1 day. To do that you know that you hike 52 miles in 3 days. 52 divided by 3 is 17.33. you will hike 17.33 miles every day.

Solve for x. Write both solutions, separated by a comma. 8x^2+7x-1=0
Ivan

Answer:

<h2>x = 1/8 , - 1</h2>

Step-by-step explanation:

8x² + 7x - 1 = 0

Rewrite 7x as a difference

That's

8x² + 8x - x - 1 = 0

Factorize

8x( x + 1) - ( x + 1) = 0

(8x - 1)( x + 1) = 0

8x - 1 = 0 x + 1 =0

8x = 1 x = - 1

x = 1/8

The solutions are

<h3>x = 1/8 , - 1</h3>

Hope this helps you

5x + 4(4x + 11) = 170 pearson realize
Jobisdone [24]

x=6

if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170

next combine like terms and get 21x+44=170

next subtract 44 from itself and 170 to get 21×=126

finally divide 21 from both sides and you get x=6

hope this helps!

The length of the hypotenuse of a 30-60-90 triangle is 28 m. Find the length of the side opposite the 30 angle
____ [38]
The answer is 14 m

<span>In a 30°-60°-90° triangle, the hypotenuse (c) is twice the length of the shorter leg (a) which is the opposite to the 30 angle:
</span>

c = 2a


We have c = 28 m

So: 28 = 2a

      a = 28 / 2 

     a = 14 m

Find the area of the following shape. you must show all work to receive credit.
Margaret [11]

Answer:

<h2>A = 57</h2>

Step-by-step explanation:

Use the Pick's theorem

Let P be a polygon in the plane whose vertices have integer coordinates. Then the area of P can be determined just by counting the lattice points on the interior and boundary of the polygon!

In fact, the area is given by

A=i+\dfrac{b}{2}-1

where <em>i</em> is the number interior lattice points, and<em> b</em> is the number of boundary lattice points.

Look at the picture.

i=50,\ b=16

Substitute:

A=50+\dfrac{16}{2}-1=50+8-1=57
