Answer:$32


Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.

Gina looked at the architectural plan of a room with four walls in which the walls meet each other at right angles. The length o
Lerok [7]

For a better understanding of the solution provided here, please find the diagram attached.

In the diagram, ABCD is the room.

AC is the diagonal whose length is 18.79 inches.

The length of wall AB is 17 inches.

From the given information, we have to determine the length of the BC, which is depicted a x, because for the room to be a square, the length of the wall AB must be equal to the length of the wall BC.

In order to determine the length of the wall BC, or x, we will have to employ the Pythagoras' Theorem here. Thus:

x=\sqrt{(AC)^2-(AB)^2}

x=\sqrt{(18.79)^2-(17)^2}\approx\sqrt{64.06} \approx8

Thus, BC\approx 8 inches

\therefore AB\neq BC and hence, the given room is not a square.

kykrilka [37]

Answer:

x= 3.57

Step-by-step explanation:

32 ( x + 2.5) = 114.24

32* x + 32* 2.5= 114.24

32x + 80= 114.24

        -80      -80

32x= 114.24

/ 32    /32

x= 3.57

for the part that says convince me, we can use the eqution
