Ok so we know that student tickets cost $5, and adult tickets cost $8. We also know that the total no. of tickets sold was 150.

Let's make the amount of student tickets sold be S, and the no. of adult tickets sold be A.

We know that tickets sales amounted to $1,020, so:
8A + 5S = 1020
And:
A + S = 150. Multiply this by 5;
5A + 5S = 750

When you subtract the two equations;
(8A+5S) - (5A+5S) = 1020-750
So 3A = 270
A = 90
So 90 adult tickets were sold.
S = 150 - 90
= 60
So 60 student tickets were sold (although you don't need this as part of your answer)

Hope this helped

Complete the square on the following quadratic x2+10x+9=0

kakasveta [241]

Given a quadratic equation $x^{2} +ax+c=0$

1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.

In our case the coefficient of x is 10, so we write 10 as 2*5

2. then we write + $5^{2}$ and - $5^{2}$ to the expression:

$x^{2} +2*5*x+ 5^{2} -5^{2}+9=0$

$(x^{2} +2*5*x+ 5^{2}) -25+9=0$

$(x+5)^{2}-16=0$

Answer: $(x+5)^{2}-16=0$

What causes global convection current to form

hoa [83]

Answer:

Hope this helped :)

Step-by-step explanation:

Convection flows structure in light of the fact that a warmed liquid grows, getting less thick. The less-thick warmed liquid ascents from the warmth source. ... For example, a hot radiator warms the air promptly around it. The air ascends toward the roof, pulling cooler air down from the roof into the radiator to be warmed.
