A)
Let x = sister's age
<span>Kim's age is twice that of her sister
</span>so Kim's age = 2x
<span>Kim’s age + Sister’s age = 36
equation:
x + 2x = 36

b) solve the equation </span>x + 2x = 36

x + 2x = 36
3x = 36
  x = 36 / 3
  x = 12
  Kim's age = 2x = 2(12) = 24


answer
Sister's age is 12 and  Kim's age is 24.

What is the best way to answer this mixed number 7 3/4 + 1 5/6
olga_2 [115]

9514 1404 393

Answer:

  9 7/12

Step-by-step explanation:

12 is a suitable common denominator.

  (7 3/4) + (1 5/6) = (7 9/12) + (1 10/12) = (7+1) +(9/12 +10/12)

  = 8 + 19/12 = 9 + 7/12 . . . . . . change 19/12 to 1 7/12

  = 9 7/12

_____

My calculator works with mixed numbers very nicely, as many graphing calculators do.

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?
Elena L [17]

Answer:

y + 7 = \frac{1}{2} (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = \frac{1}{2} and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = \frac{1}{2} (x - (- 6) ) , that is

y + 7 = \frac{1}{2} (x + 6)

Answer: 729

Step-by-step explanation:

\frac{1}{3^{-2} * 3^{-4} * (-1)^{2}  }

3^-2 = 1/9

3^-4 = 1/81

(-1)^2 = 1

1/(1/9 * 1/81 * 1)

1/ 1/729 = 729
