Solve. 3x + 3 &lt; 93- 6
AlladinOne [14]

Well this is easy.

We have linear inequality,

3x+3 < 93 -6

Simplifying this a bit to get,

3x < 84

Divide by 3 (both sides),

x < 28

Or with interval notation, x\in (-\infty, 28).

Hope this helps. :)

Answer:

5100 cm of wax will make 17 candles

Step-by-step explanation:

Each candle is 5 cm long, 4 cm wide, and 15 cm tall

to know the space they cover, we divide it with their volume and since they are in rectangular prism

Volume is length x width x height

5 x 4 x 15 = 20 x 15 = 300cm

1 candle = 300cm

what number of candle is represented as x

1 candle comprises of  300cm wax

x = 5100

300x = 5100 x 1 =5100

300x= 5100

x= 5100/300 = 17

5100 cm of wax will make 17 candles
