A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;

A chef got 7 bags of onions. The red onions came in bags of 8 and the yellow onions came in bags of 3. If the chef got a total o
frutty [35]

Answer:

\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3

Step-by-step explanation:

Let a be the number of bags with 8 onions and let b be the number of bags with 3 onions. We have the following system of equations:

\begin{cases}a+b=7,\\8a+3b=41\end{cases}

Subtracting b from both sides of the first equation, we get a=7-b. Substitute this into the second equation:

8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}

Therefore, the number of 8-onion bags is:

a=7-b,\\a=7-3,\\a=\boxed{4}

Thus, the chef got 4 8-onion bags and 3 3-onion bags.
