Please help me write the equation for the problem below

1 answer:

8 0

Since you want both sides to equal each other, you can set up the following equation:

chess club members = computer club members

500 - 30x = 150 + 20x

x represents the amount of years that have passed. The coefficients for x represent the loss or gain of members per year.

Add 30x to both sides.

500 = 150 + 50x

Subtract 150 from both sides.

350 = 50x

Divide both sides by 50 to solve for x.

x = 7

It will take 7 years for both clubs to have the same amount of members.

To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, mea

Vikki [24]

Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
$tan\:26^{\circ} =\frac{AE}{120}$
So,
$AE=120\:tan\:26^{\circ}$
$AE=58.53\:$

Therefore, the overall height of the pole is
$AB=58.53+8=66.53\:feet$

The height of the pole is 66.53 feet.

What is the answers to the question: Which rational expression is undefined when x = 0?

Rom4ik [11]

Answer:

option D

$\frac{4x-8}{-2x^2}$

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

$\frac{5(0)-4)}{3(0)-3}$

-4/-3 = 4/3

$\frac{6(0)}{9(0)-3}$

0/-3 = 0

$\frac{8x+6}{-x^2+1}$

$\frac{8(0)+6}{-0+1}$

6/1

$\frac{4x-8}{-2x^2}$

$\frac{4(0)-8}{-2(0)}$

<h3>-8/0</h3><h3>undefined</h3>

Which of the following is between 0.40 and 0.47?

tatyana61 [14]

The answer is C. 21/50 is 0.42. 7/50 is 0.14. 19/50 is 0.38. 43/50 is 0.86. To convert a fraction to a decimal, you will have to divide the numerator by the denominator.
Hope this helped.
