Round the numbers to the nearest ten thousand:
63,000 km & 20,000 km
Then find the difference (subtract):
63,000 km - 20,000 km = 43,000 km
Don't forget to put the unit of measurement on there (km)
Hope this helps :)

Solve for x.<br> −x+8=−9<br> Enter your answer as a number, like this: 42
Ymorist [56]

Answer:

x=17

Hope it helps;)

Step-by-step explanation:

Subtract 8 from both sides of the equation

-x+8=9

-x+8-8=9-8

Simplify

Subtract the numbers

x= -17

Divide both sides of the equation by the same term

x= 17

-x/-1= -17/-1

Simplify

Cancel terms that are both in the numerator and denominator

Divide the numbers

x = 17

5x - 4 &gt; 12 or 12x + 5&lt; -4?
Charra [1.4K]

Answer:

3.2 and -0.75

Step-by-step explanation:

5x - 4 > 12

add 4 to the both sides

5x > 12 + 4

5x > 16

divide both sides by 5

x > 16/5

x > 3.2

12x + 5< -4

subtract 5 from both sides

12x < -9

divide both sides by 12

x < -0.75

The length of a rectangular garden is three times its width, w. The area of the garden is 300 m². Explain why the expression 3w
kogti [31]

If the length is three times the width and the area of the rectangle is

300 m^{2} then the length of rectangle is 30m and width be 10m.

Given that the length is three times the width and the area of the rectangle is 300 m^{2}.

We are required to find the length and breadth of the rectangle.

Area of the rectangle is basically the product of length and breadth.

let the breadth of rectangle be w.

The length of rectangle will be 3w.

Area=Length*Breadth

300=3w*w

300=3w^{2}

100=w^{2}

w=+10,-10 but ignore -10 because width cannot be negative.

Length=3w=3*10=30m

Width=w=10m

The area can be written as 3w^{2} because the area of rectangle is product of length and breadth.

Hence if the length is three times the width and the area of the rectangle is  300 m^{2} then the length of rectangle is 30m and width be 10m.
