$= 2x = \frac{1}{8 } \\ = x = \frac{1}{2 \times 8} \\ = x = \frac{1}{16}$ $3x \times 9 = 81 \\ 3x = \frac{81}{9} \\ x = \frac{9}{3} \\ x = 3$

Heres your answer girlfriend ♥️♥️

Two roller coasters are vying for the title of the steepest drop the first ride has a hill that drops 140 feet in a 40 foot run

muminat

Answer:

They have the same slope

Step-by-step explanation:

Given

Coaster 1:

$Drops = 140ft$

$Run = 40ft$

Coaster 2:

$Drops = 105ft$

$Run = 30ft$

First, we calculate the slope (m) of both coasters

$m = \frac{Rise}{Run}$

$m = \frac{Drops}{Run}$

For coaster 1:

$m = \frac{140ft}{40ft}$

$m = \frac{140}{40}$

$m = 3.5$

For coaster 1:

$m = \frac{105ft}{30ft}$

$m = \frac{105}{30}$

$m = 3.5$

$m = m=>3.5 = 3.5$

By comparison, they have the same slope

(x+2y = 10 16y=-3x+30

Harlamova29_29 [7]

Answer:

x = 10, y = 0

Step-by-step explanation:

x + 2y = 10

x = 10 - 2y (Bring the 2y to the right)

16y = -3x + 30

16y = -3(10 - 2y) + 30 (Substitute x to 10 - 2y)

16y = -30 + 6y + 30 (Expand brackets)

10y = 0 (Bring y to the left)

y = 0

x = 10 - 2(0) (Substitute y = 0)

x = 10

x = 10, y = 0

Julissa wants to find the perimeter of her bedroom that is similar to her brother's. If her brother's bedroom is 12 ft long and

tatuchka [14]

I’m guessing that her room is 10ft long and 12ft wide
Because it is similar

To find perimeter, you add.
10 + 10 + 12 + 12
44ft
So about 40ft

Hope this helps :D
