Find the missing value for X
castortr0y [4]
If we assume that BC is bisecting AD, and that AE is half of AD, we can set up the equation:

2(19)=5x-7

Then we can solve directly for x:

38=5x-7
45=5x
x=9

So we have then calculated x which is equal to 9.

Six people are standing in line for concert tickets. Their average age is 27. The average age of the first four people in line i
DanielleElmas [232]

The best answer for this question would be:

 

D. 32

 

In order to get this, you have to get the sum in the line, which is the first four people. So the solution would be: 4(23) = 92

 

For getting the sum of the people in the last 3 would be: 3(34) = 102

 

Next is the sum of everyone which the solution would be: 6(27) = 162

 

So the initial solution that we have now would be: F + 92 - F + 102- F = 162

 

- F + 194 = 162

 

- F = 162 - 194

 

- F = - 32

 

The (F) here or the fourth person’s age would be= -32 / - 1 or 32

Vince has a rectangular rug in his room with an area of 10 ft the length of the rug is 18 inches longer than the width what coul
aev [14]

The length of the rug is 4 ft.

The width of the rug is 2.5 ft.

Explanation:

The area of the rug is 10 ft.

The length of the rug be l.

Let us convert the inches to feet.

Thus, 18 inches =  1.5 ft

Thus, the length of the rug is l=1.5+w

Let the width of the rug be w.

Substituting these values in the formula of area of the rectangle, we get,

A=length\times width

10=(1.5+w)(w)\\10=1.5w+w^2\\w^2+1.5w-10=0

Solving the expression using the quadratic formula,

$w=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Substituting the values, we have,

$w=\frac{-15 \pm \sqrt{15^{2}-4 \cdot 10(-100)}}{2 \cdot 10}\\

$w=\frac{-15 \pm \sqrt{4225}}{20}$

$w=\frac{-15 \pm 65}{2 0}$

Thus,

w=\frac{-15 + 65}{2 0}\\w=\frac{50}{20} \\w=2.5  and   w=\frac{-15 - 65}{2 0}\\w=\frac{-80}{20} \\w=-4

Since, the value of w cannot be negative, the value of w is 2.5ft

Thus, the width of the rug is 2.5ft

Substituting w=2.5 in l=1.5+w, we get,

l=1.5+2.5\\l=4

Thus, the length of the rug is 4 ft.
