Answer:

x = 20

Step-by-step explanation:

Assuming that both 6x and 120 are equal to each other, you can use simple algebra to find out what x is

6x = 120 (divide both sides by 6 to isolate x)

x = 20

Please answer the problem below.<br><br> ~Thanks = )
RoseWind [281]

Hi GlaxyCraft4991,

Solution:

−12x − 0.4 > 0.2 (36.5x + 80) − 55

−12x − 0.4 > 7.3x − 39

−12x − 0.4 − 7.3x > 7.3x − 39 − 7.3x

−19.3x − 0.4 > −39

−19.3x − 0.4 + 0.4 > −39 + 0.4

−19.3x > −38.6

−19.3x/19.3 > −38.6/19.3

x < 2

Correct Answer:

x < 2

Answer:

10m x 15m

Step-by-step explanation:

You are given some information.

1. The area of the garden: A₁ = 150m²

2. The area of the path: A₂ = 186m²

3. The width of the path: 3m

If the garden has width w and length l, the area of the garden is:

(1) A₁ = l * w

The area of the path is given by:

(2) A₂ = 3l + 3l + 3w + 3w + 4*3*3 = 6l + 6w + 36

Multiplying (2) with l gives:

(3) A₂l = 6l² + 6lw + 36l

Replacing l*w in (3) with A₁ from (1):

(4) A₂l = 6l² + 6A₁ + 36l

Combining:

(5) 6l² + (36 - A₂)l +6A₁ = 0

Simplifying:

(6) l² - 25l + 150 = 0

This equation can be factored:

(7) (l - 10)*(l - 15) = 0

Solving for l we get 2 solutions:

l₁ = 10, l₂ = 15

Using (1) to find w:

w₁ = 15, w₂ = 10

The two solutions are equivalent. The garden has dimensions 10m and 15m.

triangular park ABC has sides 3 m, 5 m, and 6 m. a gardener ravi wants to put a fence all around it and also plant grass inside.
Mariana [72]

Step 1) Check if the given triangle lengths form a right triangle

3^2 + 5^2 = 6^2

9 + 25 = 36

36 = 36

Step 2) Solve for the area of the triangle

Formula: A = 1/2 x base x height

A = 1/2 x 3 x 5

A = 1/2 x 15

A = 7.5 m^2

Step 3) Solve for the perimeter of the triangle

Formula: P = sum of all sides

P = 3 + 5 + 6

P = 14 m

Ravi needs to plant 7.5m^2 of grass and put up a fence that is 14m in total length.

Hope this helps!! :)
