Answer:

3 3/5 =x

3 .6 =x

Step-by-step explanation:

6/5 = x/3

Use cross products

6*3 = 5*x

18 = 5x

Divide each side by 5

18/5 = 5x/5

18/5 =x

3 3/5 =x

Answer: 3.6 = x

Step-by-step explanation: To solve for x in the given proportion, we simply use the means-extremes property which states the the product of the extremes, (6)(3), equals the product of the means, (5)(x).

So we have (6)(3) or 18 equals (5)(x) or 5x.

So we have the equation 18 = 5x.

Now dividing both sides by 5, <em>3.6 = x</em>.

Traveling with a speed of 70 mph, a car covered a distance D miles in T hours. Write an equation that relates the distance D thi

irina [24]

Answer:

Part A) $D=70T$

Part B) $D=105\ miles$

Step-by-step explanation:

Par A) Write an equation that relates the distance D this car travels in T hours

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

The speed is a proportional relationship between the distance and the time

Let

D ----> the distance in miles

T ----> the time in hours

$D=kT$

In this problem the constant of proportionality k represent the speed of the car in miles per hour

we have

$k=70\ mi/h$

substitute

$D=70T$

Part B) Use the equation to find the distance the car travels between 3:30 p.m. and 5:00 p.m

we know that

The time between 3:30 p.m. and 5:00 p.m is equal to

5:00 p.m-3:30 p.m=1.5 hours

For T=1.5 h

substitute in the equation and solve for D

$D=70(1.5)$

$D=105\ miles$

Write an equation in point-slope form for each line.<br> (If possible please show work)

Free_Kalibri [48]

Answer:

slope is calculated this way:

$\frac{3 - 6}{2 - 1} = \frac{ - 3}{1} = - 3$

let's calculate y init by:

3 = -3×2 + b

b = 9

so equation is:

y=-3x+9
