Question

Anyone help will get rewarded with medals!!!

Please!

Answer 1

The restrictions for the graph is
\[4A+3B \le 25\]
and
\[2A+B \le 30\]

Because 4 hours of pasting A wood + 3 hours of pasting B wood MUST be LESS than total pasting time 25 HR.
and

2 hr of pressing A wood + 1 hr of pressing B wood MUST be LESS than total pressing time of 30

They're asking if
A=3
B=4
is true to the equation, so plug those in.

\[4(3) + 3(4) \le 25\]
\[2(3) + 4 \le 30\]

Can you give me the answer? Are the equations true?

Answer 2

\[12 + 12 \le 25\]
\[24 \le 25\]
Therefore the first inequality is not true

\[12 + 5 \le 30\]
\[15 \le 30\]
Therefore the second inequality is not true either... right?

Answer 3

the first inequality IS true.

24 is less than or equal to 25. It is less than 25. (note: less than or equal to means it can be EITHER less OR equal. Doesn't have to be both)

the second inequality is also true.

15 is less than 30. true.

Answer 4

oh i was thinking of them as equations so im SOO sorry

Answer 5

nothing to be sorry about! The most important thing is not getting the right answer, but understanding the concept! :)

So seems like it's B ^^

Answer 6

THANKS SOO MUCH!!!
