After adding an 8-pound box with 6 identical boxes, the crate weighed 72 boxes
damaskus [11]

After adding 8 students to each of 6 same-sized teams, there were 72 students altogether.

After adding an 8-pound box of tennis rackets to a crate with 6 identical boxes of ping pong paddles, the crate weighed 72 pounds.

The first situation has all equal parts, since additions are made to each team. An equation that represents this situation is 6( x + 8 ) = 72, where x represents the original number of students on each team. Eight students were added to each group, there are 6 groups, and there are a total of 72 students.

In the second situation, there are 6 equal parts added to one other part. An equation that represents this situation is 6x + 8 = 72, where x represents the weight of a box of ping pong paddles, there are 6 boxes of ping pong paddles, there is an additional box that weighs 8 pounds, and the crate weighs 72 pounds altogether.

In the first situation, there were 6 equal groups, and 8 students added to each group. 6( x + 8 ) = 72.

In the second situation, there were 6 equal groups, but 8 more pounds in addition to that. 6x + 8 = 72.

On a map, the distance between Greenville and Fairview is 7 1/4 inches. If the map uses a scale of 1/2 inch = 40 miles, what is
lubasha [3.4K]

The actual distance between cities is 580 miles.

Step-by-step explanation:

Map distance = 7\frac{1}{4} inches = \frac{29}{4}\ inches

Scale used;

\frac{1}{2}\ inches = 40\ miles

Multiplying both sides by 2

2*\frac{1}{2}=40*2\\1\ inch = 80\ miles\\

Now,

\frac{29}{4}\ inches = \frac{29}{4}*80\\\\\frac{29}{4}=29*20\\\\\frac{29}{4}\ inches = 580\ miles

The actual distance between cities is 580 miles.

I cant seem to get one of these answers when i work it out. please help​
lisov135 [29]

Answer:

first option

Step-by-step explanation:

To obtain ( f ○ g)(x) substitute x = g(x) into f(x) , that is

f(\frac{1}{2x} )

= \frac{2}{\frac{1}{2x}+3 } ( multiply numerator/ denominator by 2x to clear the fraction

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

= \frac{4x}{1+6x}
