'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 area of the fence is 6*25=150 square feet.
It will take him 150 / 2 = 75 of 10-minute intervals. 75 min *10 = 750 min = 750/60 hours = 12.5 hours.

The yearly cost y for driving a certain car is $7,800 for 10,000 miles
Licemer1 [7]

Answer:

y = 0.36x + 4200.00

15100.00 miles.

Step-by-step explanation:

If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).

So, the equation will be

\frac{y - 11400}{11400 - 7800} = \frac{x - 20000}{20000 - 10000}

⇒ \frac{y - 11400}{3600} = \frac{x - 20000}{10000}

⇒ y - 11400 = \frac{9}{25}(x - 20000)

⇒ y - 11400 = \frac{9}{25}x - 7200

⇒ y = \frac{9}{25}x + 4200

⇒ y = 0.36x + 4200.00 ........... (1) (Answer)

Now, for y = $9636.00, from equation (1),

9636 = 0.36x + 4200

⇒ 0.36x = 5436

⇒ x = 15100.00 miles. (Answer)
