What is x when 1/7 + x = 2/3x

2 answers:

7 0

1/7+x=2/3x
x+1/7=2/3x
21x + 3 = 14x
21x = 14x-3
21x-14x= -3
7x = -3
x = -3/7

Therefore, the value of x is -3/7

X-2/3x= - 1/7 is equivalent to the equation above. Then you get 1/3x= - 1/7.
So, x = - 3/7

A draw is an advance that need not be repaid if the commission does not exceed the draw. True or false?

attashe74 [19]

True, for each month throughout the draw period the company will pay the sales representative the draw amount if the sales representative made commissions that are less than the draw amount. the remaining draw amount accumulates from month to month. But when received commissions exceed the draw, this is the case that the extra commissions will be used to repay the outstanding draw. Once the gathered draw is repaid all commissions are compensated to the sales representative.

A TV screen is 41 cm long and 31 cm high. The length of the diagonal is closest to: A) 49 cm Eliminate B) 51 cm C) 54 cm D) 48 c

GuDViN [60]

Answer:

The length of the diagonal is closest to 51 cm.

Step-by-step explanation:

Given:

TV screen is 41 cm long and 31 cm high.

Now, to find the length of the diagonal.

By using pythagorean theorem:

leg 1 = 41 cm, leg 2 = 31 cm.

Let the hypotenuse be $x$ .

(leg 1)² + (leg 2)² = hypotenuse²

$41^{2} +31^{2}=x^{2}$

⇒ $1681+961=x^{2}$

⇒ $2642=x^{2}$

Using square root on both sides we get:

⇒ $51.40=x$

So, the length of the diagonal = 51.40 cm.

By rounding off of 51.40cm it becomes 51 cm.

Therefore, the length of the diagonal is closest to 51 cm.

Use the the factor theorem to determine wether the first polynomial is a factor of the second. X-3; 2x^2-4x+30

Firdavs [7]

Given the polynomial function

$P(x)=2 x^{2} -4x+30$

If (x-3) is a factor of P(x), then

$P(x)=2 x^{2} -4x+30=(x-3)*Q(x)$ , for some polynomial Q of 1st degree,

Then according to the factor theorem P(3)=0, because P(3)=(3-3)Q(x)=0*Q(3)=0.

Check

$P(3)=2 (3)^{2} -4(3)+30=18-12+30=36$ ≠0

we see that P(3) is not 0, so (x-3) is not a factor of P(x).

Complete this table showing the number of shaded triangles in each step and area of each triangle!

djverab [1.8K]

Answer:

Step-by-step explanation:

From the table attached we find,

Number of shaded triangles = 1

Area of each shaded triangle = 256 square inches

Now we can complete the table following the same pattern,

Step number Number of shaded triangles Area of the shaded triangles

0 1 256

1 3 256 × 3 = 768

2 5 256 × 5 = 1280

3 7 256 × 7 = 1792
