Answer:

-6 ≥ x

Step-by-step explanation:

x + 6 ≥ 12 + 2x

Subtract x from each side

x-x + 6 ≥ 12 + 2x-x

6 ≥ 12 + x

Subtract 12 from each side

6-12 ≥ 12-12x

-6 ≥ x

Answer:

x≤-6

Step-by-step explanation:

x+6≥12+2x

subtract 2x from both sides

-x+6≥12

subtract 6 from both sides

-x≥6

Now divide by -1, remember to switch signs because its negative.

x≤-6

A car is traveling at a steady speed. It travels 1 1/2 miles in 2 1/4 minutes. How far will it travel in 41 minutes? In 1 hour

Ganezh [65]

Answer:

The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour.

Step-by-step explanation:

First, find how far the car can travel in one minute.

(1 1/2)/(2 1/4)=(2/3)

Then multiply the amount of time in minutes.

(2/3)*44= 29 1/3

(2/3)*60=40

The variable x varies directly as the cube of y, and y varies directly as the square root of z. If x equals 1 when z equals 4, w

Aloiza [94]

Answer:

Step-by-step explanation:

According to the question,

$x$ ∝ $y^3$ .......(1)

$y$ ∝ $\sqrt{z}$ .......(2)

From equation 1,2 let constant of proportionality be $k1,k2$ respectively.

⇒ $x=k1(y^3)$ .......(3)

⇒ $y=k2(\sqrt{z} )$ .......(4)

From the above equations putting 4 into 3,

$x=k1((k2\sqrt{z})^3) =k1.k2^3.(\sqrt{z})^3$

Let the new constant to the above equation be $k3$ ,

$x=k3(\sqrt{z})^3$

Given,if x=1, when z=4

$1=k3(\sqrt{4} )^3=k3(8)$

⇒ $k3=\frac{1}{8}$

Now if x=27, then z=?

$27=\frac{1}{8} (\sqrt{z} )^3$

⇒ $(\sqrt{z} )^3=27(8)$

⇒ $\sqrt{z}=3(2)=6$

$z=36$

HELP FAST!!! Here are two rectangles. The length and width of one rectangle are 8 and 5. The width of the other rectangle is 5,

deff fn [24]

Answer:

5•x=? and 8•5=40, personal opinion: the left rectangle is most likely a square so if you need to solve it it's 5•5=10

Step-by-step explanation:

A(area)=l (length)•w (width)

just plug in your numbers, in this case it would be 8(length) times 5(width)
