How many solutions does the following equation have?<br> -2z+10+7z=16z+7

lorasvet [3.4K]

Start with

$-2z+10+7z=16z+7$

Simplify the left hand side by summing like terms (the one involving z):

$5z+10 = 16z+7$

Subtract 5z from both sides:

$10 = 11z+7$

Subtract 7 from both sides

$3 = 11z$

Divide both sides by 11:

$z = \dfrac{3}{11}$

Since the area of the walkway is not given, it's substitution in the answer is x. You do have the measurements of the pool though. Area=length times width. 36 times 18 is 648. The area of the concrete is x-648 ft, because the pool is not apart of the concrete. The area of the walkway can be expressed by X-648 ft.

Calculate the loss on selling 50 shares of stock originally bought at 133/4 and sold at 12.

Anarel [89]

Here is the solution of the given problem above:
The first thing we should do is to multiply 50 and 13 3/4
13 3/4 is equivalent to 13.75 .
So, we then multiply
50 x 13.75 and we get 687.50.
so, $687.50 was the amount spent on the stock.
Now, lets find out how much they sold them for:
What we do is multiply 12 and 50
50 x 12 would be 600
We can find out the loss by subtracting
$687.50 - $600 and that gives us $ 87.50.
Therefore, the amount that is loss in selling is $87.50. The correct answer would be option B. Hope this answer helps.

choli [55]

Answer:

The number of children's tickets sold was 31 and the number of adult tickets sold was 2

Step-by-step explanation:

Let

x ---> the number of children's tickets sold

y ---> the number of adult tickets sold

we know that

the theater sold 33 tickets

$x+y=33$ -----> equation A

the theater made a total of $158.50

$4.50x+9.50y=158.50$ ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (31,2)

see the attached figure

therefore

The number of children's tickets sold was 31 and the number of adult tickets sold was 2
