Answer:

a) System of equations will be: $x+y=500\: and\:5x+2y=1789$

b) Number of adult tickets sold = 263

Number of students tickets sold = 237

Step-by-step explanation:

Let:

Number of adult tickets sold = x

Number of students tickets sold = y

As Marc sold total 500 tickets, the expression will be: $x+y=500$

Student tickets cost $2 and adult tickets cost $5. Marc's sales totalled $1,789.

The expression will be: $5x+2y=1789$

So, system of equations will be: $x+y=500\: and\:5x+2y=1789$

Solve the system to find value of x and y

Let:

$x+y=500--eq(1)\\5x+2y=1789--eq(2)$

Multiply equation 1 by 2 and subtract

$2x+2y=1000\\5x+2y=1789\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\------\\-3x=-789\\x=\frac{-789}{-3}\\x=263$

We get value of x = 263

Now finding value of y by putting value of x in eq(1)

$x+y=500\\263+y=500\\y=500-263\\y=237$

We get value of y = 237

Number of adult tickets sold = x = 263

Number of students tickets sold = y = 237

What is the answer for 3912.99/15.9

san4es73 [151]

The question asks the answer that comes out from the division of 3912.99 by 15.9. Both the numbers are in decimal form, so the division will be easy.
3912.99/15.9
= (391299 * 10)/(159 * 100)
= (391299)/(1590)
= 246.10
So the answer that comes out from the division of the two numbers given in the question is 246.10. I hope i have described the full process and it has helped you to understand the way these kind of problems need to be tackled.

Solutions to equation x^2 + x - 30 = 12 using zero product property

Likurg_2 [28]

Answer:

Our solutions are x= -7 , x=6

Step-by-step explanation:

x²+x-30=12

First we calculate the constants:

x²+x-30-12=0

x²+x-42=0

Now split the middle term:

x²+7x-6x-42=0

x(x+7)-6(x+7)=0

(x+7)(x-6)=0

As we know that:

a.b=0

⇒either a=0 or b=0

(x+7)=0 , (x-6)=0

x=0-7 , x=0+6

x= -7 , x=6

So our solutions are x= -7 , x=6....
