Answer:

The midpoint is ( 1, -1.5)

Step-by-step explanation:

To find the midpoint

Add the x coordinates of the endpoints and divide by 2 to get the x coordinate of the midpoint

(5+-3)/2 = 2/2 = 1

Add the y coordinates of the endpoints and divide by 2 to get the y coordinate of the midpoint

(3+-6)/2 = -3/2 = -1.5

The midpoint is ( 1, -1.5)

Answer:

mid point = 1,  -1.5

Step-by-step explanation:

mid point between two points C(5, 3) and D(-3, -6)

M = (x1 + x2)/2  , (y1 + y2)/2

mid point = (5 + (-3)) / 2 ,  (3 + -6)/2

mid point = 2/2 , -3/2

mid point = 1,  -1.5

A train traveled 210 mi in 3.5 h to its first stop. It then continued on traveling another 130 mi in 2.5 h.
11111nata11111 [884]

Answer:

56.7 ​ mi/h​


Step-by-step explanation:

The formula for average speed is:

Average Speed = \frac{TotalDistance}{TotalTime}


Thus we have:

Average Speed = \frac{210+130}{3.5+2.5}\\=\frac{340}{6}\\=56.66 mph


<em>Rounding to the nearest tenth, we have </em>

Average Speed = 56.7 mi/h

Ivanshal [37]

Answer:

1/3 of the pizza remains.

Step-by-step explanation:

Matthew eats 1/3 of 1/2 of the pizza, which is (1/3)*(1/2) = 1/6 of the pizza.  The amount of pizza left is

1/2 - 1/6 = 3/6 - 1/6 = 2/6 = 1/3

1/3 of the pizza remains.

Which values of x satisfy the inequality 0.5 x minus 0.75 greater-than-or-equal-to 3.25?
mr_godi [17]

Answer:

x ≥8

Step-by-step explanation:

Given inequality

0.5x - 0.75 ≥ 3.25

Adding 0.75 to both sides

0.5x -0.75 +0.75 ≥ 3.25 + 0.75

0.5x ≥ 4

Divide both sides by 0.5

(0.5x) / (0.5) ≥ (4) /(0.5)

x ≥ 8
