Ganezh [65]

She sold 74 child tickets and 126 adult tickets

Step-by-step explanation:

Stacy is selling tickets for the school play

She has a total of 200 seats available, and there will be two types of tickets offered, child and adult tickets
She sold each child ticket for $6 , each adult ticket for $10 , and made a total of $1704

We need to find how many of each ticket she sold

Assume that x is the number of child tickets and y is the number of the adult tickets

∵ She has a total of 200 seats available

∵ She sold x child tickets

∵ She sold y adult tickets

- Add x and y, then equate the sum by 200

∴ x + y = 200 ⇒ (1)

∵ She sold each child ticket for $6

∵ She sold each adult ticket for $10

∵ She made a total of $1704

- Multiply x by 6 and y by 10, then add the products and

equate them by 1704

∴ 6x + 10y = 1704 ⇒ (2)

Now we have a system of equation to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -2000 ⇒ (3)

- Add equations (2) and (3) to find x

∴ -4x = -296

- Divide both sides by -4

∴ x = 74

- Substitute the value of x in equation (1) to find y

∵ 74 + y = 200

- Subtract 74 from both sides

∴ y = 126

She sold 74 child tickets and 126 adult tickets

Answer:

$\textbf{Hello!}$

$\Longrightarrow2^2+2z=0$

$\Longrightarrow x_{1,\:2}=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:0}}{2\cdot \:1}$

$\Longrightarrow \sqrt{2^2-4\cdot \:1\cdot \:0}$

$\Longrightarrow =\sqrt{2^2-0}$

$\Longrightarrow =\sqrt{2^2}$

$\Longrightarrow=2$

$\Longrightarrow x_{1,\:2}=\frac{-2\pm \:2}{2\cdot \:1}$

$\Longrightarrow x_1=\frac{-2+2}{2\cdot \:1},\:x_2=\frac{-2-2}{2\cdot \:1}$

$\Longrightarrow\frac{-2+2}{2\cdot \:1}$

$\Longrightarrow =\frac{0}{2\cdot \:1}$

$\Longrightarrow =\frac{0}{2}$

$=0$

$\Longrightarrow\frac{-2-2}{2\cdot \:1}$

$\Longrightarrow =\frac{-4}{2\cdot \:1}$

$\Longrightarrow =\frac{-4}{2}$

$\Longrightarrow =-\frac{4}{2}$

$=-2$

$x=0,\:x=-2\Longleftarrow$

Need help number 18,19

cupoosta [38]

18) Seven less than the product of a number z and 3 is equal to 4

Product of a number z and 3 ⇒ 3z

Seven less than^ ⇒ 3z - 7

Equal to 4 ⇒ = 4

3z - 7 = 4

________________________________________________________

19) Make an equation for this problem. Your equation will look like:

d + 132 = 468, where d + 132 is the distance she drove on Monday and 468 is the distance she drove on Tuesday.

Solve the equation for d by subtracting 132 from both sides.

d = 336

The truck driver drove 336 miles on Monday, so that means she did not drive 600 miles on Monday.
