Answer:
Sarah bought 2 coach tickets and 3 first class tickets. 
Step-by-step explanation:
Let c and f represent the numbers of coach and first class tickets purchased.  Then c + f = 5, so that c = 5 - f.
The pricing equation is therefore
$380c + $1080f = $4000.  Subbing 5 - f for c, we get the revised equation
380(5 - f) + 1080f = 4000.
After simplification, this becomes:
-380f + 1080f = 2100, or
700f = 2100.
Then f = 3 and c = 5 - f = 5 - 3 = 2.

Answer:
Slope is the change in y over the change in x. The toy airplane would then have a slope of 3/5 and the toy helicopter would have a slope of 1/2. As 3/5 is greater than 1/2, the toy airplane would have a greater slope.

'karen is making 14 different kinds of greeting cards she is making 12 of each kind how many greeting cards does she making'
 ok so that is multiplication
14 times 12 since it is 12 of each and 14 of them so 
14 times 12=
do you guys still do multiplication by the tower meathod or such if so, here it is
14
<span><u>12 x</u>
</span>
so it is 
if you had
     a    b
     <u>c</u><span><u>    d x</u></span>
     (ad)(bd)
<u>(bc)(ac)        +</u>
result
first you do 
2 times 4 then place it below the 2
14
<span><u>12 x</u>
</span> 8
then you do 2 times 1 then place it below 
14
<span><u>12 x</u>
</span>28
then you move on the the one
1 times 4
14
<span><span><u>12 x</u>
</span>28
4
then 1 times 1<span>
</span></span>  14
<span><span>  <u>12 x</u>
</span>  28
14
</span>
then we add
  14
<span><span>  <u>12 x</u>
</span>  28
<u>14    +</u></span>

The equation that shows the relationship between the number of round trips, x and the number of kilometers, y Scott walked is y = 3x
Each round trip = 3 km
x = number of rounds
y = number of km he has walked in all.
1 rounds  = 3 km
Therefore,
x rounds = 3x km
Each round of trip covers 3km. This means for each round of trip a distance of 3km is covered. The total distance or number of kilometers is represented with y. 
The equation to show the relationship between x(number of rounds) and y (number of km) can be represented below
