First do 12-5, which equals 7.  Next, subtract 1/10 from 2/5.  2/5 is the same as 4/10 if you multiply both the numerator and denominator by 2.  4/10-1/10=3/10. Now add 7 and 3/10.  You will get 7 3/10 as the answer, which is letter C.)

gogolik [260]

Answer:

D = 7

Step-by-step explanation:

To find the median, we must first list the amount of books each person read, and then put them in order.

2, 2, 7, 12, 25

These are already in order from smallest to greatest, which is awesome. We can then cross out one number from each side until we end up with either one or two numbers. We then find the average of those 1 or 2 numbers to find our median.

2, 3, 7, 12, 25

cross 2 and 25 out

3, 7, 12

cross 3 and 12 out

7

Our median is thus 7

Multi-step K is the midpoint of JL, JL=4x-2, and JK=7. Find x, KL, and JL
ddd [48]
If K is midpoint of JL then JK = 0.5JL

JL = 4x - 2; JK = 7

The equation:
0.5(4x - 2) = 7
2x - 1 = 7      |add 1 to both sides
2x = 8        |divide both sides by 2
<u>x = 4</u>

<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>

<u>KL</u> = JK =<u> 7</u>
