How do you solve an inequality that looks like 6q<-18?

1 answer:

5 0

If you're trying to find the range/inequality of q then this is how you do it:

6q < -18
divide the whole inequality by 6
(6q)/6 < (-18)/6
q < -3

Juanito looked out the window and saw 20 bicycles and skateboards. There were a total 52 wheels. How many of each did he see , s

andriy [413]

Answer:

Let's denote:

x: number of bicycles

y: number of skateboards

Then, we have:

x + y = 20

2x + 4y = 52

=> 2(20 - y) + 4y = 52

=> 2y = 12

=> y = 6 (number of skateboards)

=> x = 14(number of bicycles)

Hope this helps!

The volume of a cube is 1000mm3. What is the length of its side?

Damm [24]

A cube's volume is length * hight * width

since it is a cube, length hight width are all the same.

so we can use variable x to represent it.

x*x*x

which is
${ x}^{3}$

so

${x}^{3} = 1000$
cube root both sides

$x = \sqrt[3]{1000} = 10$

length of its side is 10
