A 39-foot-long speaker wire is to be cut into three pieces. One piece is to be 13 feet long. Of the remaining pieces, one must b
alexira [117]
39 foot into 3 pieces
one is 13 feet
 the other pieces add up to the remaining wire
 which is 39-13=26 so
 the two remaining pieces are x and y
one must be 2 less than 3 times the other
 x must be 2 less than 3 times the y
x=-2+3y
 x=3y-2
 x+y=remaining=26
 26=x+y
 x=3y-2
 subsitute
 26=3y-3+y
 add like terms
 26=4y-2
 add 2 to both sides
 28=4y
 divide by 4
 7=y
 subsitute
 7+x=26
 subtract 7
 x=19
 19>7
 7 feet is the legnth of the shorter piece

Find the lenght (L) of the pool. The total volume of a backyard pool is 3,600 cubic feet. The height of the pool is 6 ft and a w
DedPeter [7]
Assuming that the pool is a perfect rectangular prism, then its volume, V, is given by V=lwh, where l is the length, w is the width, and h is the height. Manipulate this formula first to solve for length.

V=lwh

Divide both sides of the equation by w*h.

\dfrac{V}{wh} = l

Now, plug in your values for volume, width, and height.

l= \dfrac{3,600}{(5)(6)} =  \dfrac{3600}{30} =  \dfrac{(120)(30)}{30} = 120 \ ft

The answer is 120 ft.

The speed limit is 55 minutes per hr. write an inequalit to represent the speed limit.
anygoal [31]
Answer: Either x \le 55 or 0 \le x \le 55 depending on your teacher's preference. See the note at the bottom for more info. 

=====================================

Let x be the speed limit. It is simply a placeholder. Think of it as a box with the number inside. We don't know what the number is, but we know that the largest it can be is 55. It cannot be larger than 55.

So x can be equal to 55 or it can be smaller

Put another way, x is less than or equal to 55 which is written as x \le 55 (on the keyboard you would type " x <= 55 " without quotes). 

---------------------------------------

Note: since negative speeds make no sense, we also must imply that x can't be negative. Your teacher may want you to write this in to clearly state it. If so, then you would also have x \ge 0 which when combined with the first inequality, you get this compound inequality 0 \le x \le 55 (basically saying "x is some speed between 0 and 55 mph"). This very clearly states the boundaries on what x can be. Though your teacher may want you to stick to the first format as its simpler.
