Answer:

  1. 30m +50 = 20m +100
  2. m = 5
  3. yes. symmetric property of equality.

Step-by-step explanation:

1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...

  c = 20m +100

gives you ...

  30m +50 = 20m +100

__

2. Adding -50-20m to both sides gives ...

  10m = 50

  m = 5 . . . . . . . divide by 10

__

3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...

  c = 30m +50

to get ...

  20m +100 = 30m +50

This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).

You get the same solution.

If L
BabaBlast [244]
Pythagorean's theorem says the hypotenuse of a triangle is A^2+B^2=C^2 in this case I'll put the L,W, and D so it's easy to understand. L^2+W^2=D^2 is the exact same formula as above and is how we will solve this. (30^2)+(10^2)=1000 then we take the square root since 1000=D^2, and we get 36.62 as D.

The formula
son4ous [18]

Answer:

The truck travel must to have a constant speed of 22.06\ ft/sec

Step-by-step explanation:

we have

d=1.3t^{2}+t+2

where

d expresses a car's distance in feet

t is the number of seconds

<em>Find the distance d for t=8 sec</em>

d=1.3(8)^{2}+8+2=93.2\ ft

<em>Find the distance d for t=8.2 sec</em>

d=1.3(8.2)^{2}+8.2+2=97.612\ ft

The total distance in this interval of 0.2 sec is

97.612-93.2=4.412\ ft

<em>Find the speed of the car</em>

Divide the total distance by the time

4.412/0.2=22.06\ ft/sec

therefore

The truck travel must to have a constant speed of 22.06\ ft/sec
