Acrate weighs 12kg. a candle weighs about .4kg. for shipping the crate and candles must weigh no more than 80kg. how many candles can be in the crate?

The maximum number of candle can be in crate show that shipping weigh do not get more than 80 kg is 17 .

Step-by-step explanation:

Given as :

The weight of crate = 12 kg

The weight of candle = 4 kg

Total weight including crate and candle must not more than 80 kg

So, Let the number of candle = x

Or, According to question

The weight of crate + 4 × The weight of candle = 80

or, 12  +  4 ×  x = 80

or, 4 ×  x = 80 - 12

Or, 4 ×  x = 68

∴   x =

I.e x = 17

Hence the maximum number of candle can be in crate show that shipping weigh do not get more than 80 kg is 17 . Answer

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

it is c, trust i got your back lol
