Dr. Irvine saw 130 patients in one week. The ratio of kids to adults that he saw is 3 to 7. If k represents the number of kids a
Vitek1552 [10]

Answer:

<u>The correct answer is </u>

<u>C. k+d=130 </u>

<u>7k = 3d</u>

<u>Number of kids Dr. Irvine see in a week is 39.</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Number of patients Dr. Irvine see in a week = 130

Radio of kids to adults = 3:7 or 3/7

Number of Kids = k

Number of adults = d

2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see

k + d = 130 (Number of patients Dr. Irvine see in a week)

Including the ratio:

7k = 3d

Replacing d:

d = 130 - k

Now substituting:

7k = 3 * (130 - k)

7k = 390 - 3k

10k = 390

k = 390/10

<u>k = 39</u>

Rearrange the equation so uuu is the independent variable.<br> -12u+13=8w-3
Sunny_sXe [5.5K]

Step-by-step explanation:

- 12u + 13 = 8w - 3 \\  - 12u + 13 + 3 = 8w  \\  - 12u + 16 = 8w  \\ w =  \frac{ - 12u + 16}{8}   \\ w =  \frac{ - 3}{2} u + 2

I hope that is useful for you :)

pantera1 [17]

Answer:

  18√2

Step-by-step explanation:

The area of the smaller triangle is 1/2 that of the larger one. Since the triangles are similar, the dimensions of the smaller triangle are √(1/2) those of the larger one.

  36 · √(1/2) = 36 · (√2)/2 = 18√2 . . . . length of line dividing the triangle
