Can you solve these and explain. 4x + 6 < -6. - 2/5 x-9 < 9/10
Elena L [17]

4x + 6 < -6

subtract 6 from each side

4x < -12

divide by 4

x < -3


- 2/5 x-9 < 9/10

multiply each side by 10 to get rid of the fractions

10*(- 2/5 x-9) < 10*9/10

distribute

-4x -90 <9

add 90 to each  side

-4x < 99

divide by -4 (which flips the inequality)

x> -99/4

x> -24 3/4

is it possible to store a 20 foot long pipe in a rectangular room that is 10 feet by 12 feet by 8 feet?
Anastaziya [24]
First we'll consider the floor size.
In a 10 by 12 room the longest pipe that will fit lying on the floor equals the hypotenuse of a 10 by 12 triangle:
hypotenuse² = 10² + 12²
hypotenuse² = 100 + 144
hypotenuse² = 244
hypotenuse = <span> <span> <span> 15.62 feet

Now we have to consider the third dimension (height = 8 feet).
The two sides would be 15.62 and 8
</span></span></span>hypotenuse² = 15.62² + 8²
hypotenuse² = 244 + 64 = 308
hypotenuse = 17.55
So, the longest pipe that would fit in that room would be 17.55 feet long.
