Find the number of boxes needed, x, for 42 granola bars. ​
serg [7]

The question is incomplete:

Find the number of boxes needed, x, for 42 granola bars. ​

The table with the information is attached.

Answer:

The number of boxes needed for 42 granola bars is 7.

Step-by-step explanation:

Since the table shows that for 12 granola bars 2 boxes are needed, you can use a rule of three with this information to find the number of boxes needed for 42 granola bars:

12 granola bars  → 2 boxes

42 granola bars →      x

x=(42*2)/12

x=84/12

x=7

According to this, the answer is that the number of boxes needed for 42 granola bars is 7.

Elena has a washing machine with a 20 gallon capacity. She always uses a 20 gram measure of soap for every 10 gallons of water.
baherus [9]

Answer:

For \[20\] minutes Elena add water to correct the error.

Step-by-step explanation:

The capacity of the washing machine is \[20\] gallons.

She uses \[20\] gram soap for \[10\] gallon of water

Her son by mistake dissolved \[60\] grams of soap to \[10\] gallons of water.

\[60\]-gram soap is right for \[30\] gallons of water, thus \[20\] gallon of water must be added more.

She pore water \[2\] gallons per minute thus, \[20\] gallons of water will take\[10\]minutes.

Solve 4/x-4=x/x-4-4/3 for x and determine if the solution is extraneous or not
4vir4ik [10]

<u>Answer:</u>

x = 4 (extraneous solution)

<u>Step-by-step explanation:</u>

\frac { 4 } { x - 4 } = \frac { x } { x - 4 } - \frac { 4 } { 3 } \\ \frac { 4 } { x - 4 } - \frac { x } { x - 4 } = - \frac { 4 } { 3 } \\ \frac { 4 - x } { x - 4 } = - \frac { 4 } { 3 } \\ 3 ( 4 - x ) = - 4 ( x - 4 ) \\ 1 2 - 3 x = - 4 x + 1 6 \\ 4 x - 3 x = 1 6 - 1 2 \\ x = 4 \\

This solution is extraneous. Reason being that even if it can be solved algebraically, it is still not a valid solution because if we substitute back x=4, we will get two fractions with zero denominator which would be undefined.
