Melissa walked at a rate of 88 feet per minute. what was her approximate speed to the nearest tenth of a mile per hour? 0.1 miles per hour 1.0 miles per hour 2.8 miles per hour 8.8 miles per hour

Answer:

B

Step-by-step explanation:

Slope formula: y2-y1/x2-x1

Let (-7, 2) = x1 and y1

Let (4,6) = x2 and y2

6-2/4-(-7)

4/11

Answer:

4cm

Step-by-step explanation:

Firstly, we need to know the perimeter of the rectangle so as to know the length used to make the rectangle. This is 2(l + b)

P = 2(12 + 6) = 2(18) = 36cm

The length remaining to make the hexagon would be 60 - 36 = 24cm

Now since the hexagon is regular, the length of each side would be 24/6 = 4cm

Note: hexagon is a polygon with 6 sides

Answer:

x = 1/2 = 0.5

Step-by-step explanation:

We must solve x in the following equation:

–3x + 1 + 10x = x + 4

We'll try to get the terms with x on the left and the independent terms on the right by performing the opposite operations on both sides of the equation:

–3x + 1 + 10x -x = x + 4 -x

–3x + 1 + 10x -x  -1 = 4 -1

6x = 3

Now lets isolate x, again by performing the opposite operation, that is dividing by 6 on both sides:

6x /6 = 3/6

x = 1/2 = 0.5

Answer:

7x - 5y = 3

Step-by-step explanation:

The Standard Form formula is Ax + By = C, however, technically A should not be negative, and since the original is already written in an usually accepted version of Standard Form, I would assume you would just want to multiply the entire equation by -1 making the A a positive number.
