  speed = distance/time
The average speed will be the change in distance divided by the change in time.
  (d(10) -d(5))/(10 -5) = (80 -20)/5 = 12 . . . . meters per second

And here is the other one.

Since BD bisects angle ABC, that means angle ABD and angle CBD are equal to each other. With that set up the equation to solve for x like this:

-4x+33 = 2x+81
-2x -2x
————————
-6x +33 = 81
-33 -33
————————
-6x = 48
————- (divide by -6)
-6

x = -8


Now substitute that to ABD
-4(-8) +33
32 +33
=65

here’s CBD
2(-8) + 81
-16 + 81
=65

Finally angle ABC will be double the amount of ABD or CBD so 65 times 2 is 130.

ANSWERS: (angles)
ABD and CBD: 65
ABC: 130

Peter Schmidt ordered sandwiches and salads for a luncheon meeting. The sandwiches cost three times as much as a salads. The tot
evablogger [386]

EXPLANATION

Let's see the facts:

$Sandwiches= 3*$Salads

Bill = $24.92

We can represent this in an equation:

Total Bill = Sandwiches + Salads

Let's call to Sandwiches "x" to Salads "y" and to Bill "B"

Then, the equation will be:

B = x+y = (3*y) + y

Applying distributive property:

24.92 = 3y + y

Adding similar terms:

24.92 = 4y

Dividing both sides by 4:

6.23 = y

Switching:

y=6.23

As we know, y variable represent the salads cost, so:

Answer is $6.23.

SashulF [63]

We can Notice that ∠ABC = ∠ACB

We know that if Two Angles are Equal then Angles Corresponding to those Sides are also Equal.

⇒ AB = AC

⇒ 4x + 4 = 6x - 14

⇒ 6x - 4x = 4 + 14

⇒ 2x = 18

⇒ x = 9

⇒ Length of BC = 2x + 7 = 2(9) + 7 = 18 + 7 = 25 units
