Answer:

-5.6k-7

Step-by-step explanation:

you'd start by multiplying 6 by everything in the first pair of parentheses:

6(-2.1k-2)= (-12.6k-12)

then you'd add the like terms together:

(-12.6k-12)+(7k+5)= -5.6k-7

using the midpoint formula find the coordinates of the midpoint 9f each sigment with end points (4,2),(-5,-1)​
exis [7]

Answer:

The midpoint of the segment is (-0.5,0.5).

Step-by-step explanation:

Midpoint of a segment:

The midpoint of a segment is given by the mean of its coordinates.

Segment with end points (4,2),(-5,-1)​

x-coordinates: 4 and -5

y-coordinates: 2 and -1

x-coordinate of the midpoint:

x = \frac{4-5}{2} = -\frac{1}{2} = -0.5

y-coordinate of the midpoint:

y = \frac{2-1}{2} = \frac{1}{2} = 0.5

The midpoint of the segment is (-0.5,0.5).

Answer:4^2≈50.26548

Step-by-step explanation:

   πr2.

   Where r is the radius and π≈3.14 , the ratio of a circle's circumference to    its diameter.

   Plugging in 4 from the radius, we get.

   42π

   ⇒16π inches.

   This is our exact answer. Alternatively, we can plug in 3.14 for π to get.

   50.26 inches.

Warren drives half the distance Kendall drives to work. Kendall drives 26 more miles to work than Joe. Warren drives 15 miles. W
dem82 [27]

Answer:

15 times 2 - 26 = x

Step-by-step explanation:

Warren drives half the distance Kendall drives to work. Kendall drives 26 more miles to work than Joe. Warren drives 15 miles. Write an equation that models this situation. Use x to represent the number of miles Joe drives to work.

W X 1/2 = K

K - 26 = J

so 15 times 2 - 26 = x
