Solve for x step by step. <br><br> 9/2(8-x)+36=102-5/2(3x+24)

kvasek [131]

To solve this problem you must apply the proccedure shown below:

1. Apply the Distributive property:

$\frac{9}{2}(8-x)+36=102-\frac{5}{2}(3x+24)\\\frac{72}{2}-\frac{9}{2}x+36=102-\frac{15}{2}x-\frac{120}{2}$

2. Now, you must simplify:

$36-\frac{9}{2}x+36=102-\frac{15}{2}x-60$

3. Add the like terms:

$-\frac{9}{2}x+\frac{15}{2}x=102-60-36-36\\\frac{6}{2}x=-30$

4. Simplify:

$3x=-30$

5. Solve for x. Divide -30 by 3:

$x=\frac{-30}{3}\\x=-10$

The answer is: $x=-10$

Find the distance between P(2, 8) and Q(5, 3).

swat32

Answer:

The distance (d) between two points (x1,y1) and (x2,y2) is given by the formula

d = √ ((X2-X1)2+(Y2-Y1)2)

d = √ (5-2)2+(3-8)2

d = √ ((3)2+(-5)2)

d = √ (9+25)

d = √ 34

The distance between the points is 5.8309518948453

The midpoint of two points is given by the formula

Midpoint= ((X1+X2)/2,(Y1+Y2)/2)

Find the x value of the midpoint

Xm=(X1+X2)/2

Xm=(2+5)/2=3.5

Find the Y value of the midpoint

Ym=(Y1+Y2)/2

Ym=(8+3)/2=5.5

The midpoint is: (3.5,5.5)

Graphing the two points, midpoint and distance

The length of the black line is the distance between the points (5.8309518948453)

Find the slope of the line connecting the two points

Slope = (Y2-Y1) = (3-8) = (-5) = -1.66666666666667

(X2-X1) (5-2) (3)

Find the equation of the line passing through the two points

The general equation for a straight line is

y = mx + b

Where m represents the slope of the line which we found in the previous step to be -1.66666666666667

y = -1.67x + b

We substitute x and y for the values from one of our points (2,8)

8 = -1.67×2 + b

8 = -3.33 + b

8--3.33 = b

11.33 = b

Knowing both b and m, we can contruct the equation of the line

y= -1.67x+ 11.33

X and Y intercepts

The x-intercept is a point on the graph where y is zero

Using the equation we found in the previous step and substituting zero for y

y= -1.67x+ 11.33

0= -1.67x+ 11.33

1.67x= 11.33

x= 11.33/1.67 = 6.80

The x intercept for this straight line is 6.80

The y-intercept is a point on the graph where x is zero

Using the equation we found in the previous step and substituting zero for x

y= -1.67×0+ 11.33

y= 11.33

The y intercept for this straight line is 6.80

Type A is 2 feet tall and grows at a rate of 17 inches per year. Type B is 10 feet tall and grows at a rate of 5 inches per year

Svetllana [295]

Answer:

Therefore after 3 years the height of these tree will be same.

Step-by-step explanation:

Given that,

Type A is 2 feet tall and grows at a rate of 17 inches.

Type B is 10 feet tall and is growing at a rate of 5 inches.

1 feet = 12 inches,

2 feet= (12×2) inches = 24 inches

5 feet= (12×5) inches = 60 inches

Let after t years, the height of these tree will be same.

After t years, the height of type A is =(24+17t)

After t years, the height of type B is =(60+5t)

According to the problem,

24+17t=60+5t

⇒17t-5t=60-24

⇒12t = 36

⇒t = $\frac{36}{12}$

⇒t=3

Therefore after 3 years the height of these tree will be same.
