I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
<u>-1/2x - 7 = -11</u>
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : <em> x = 8</em>
Take it Allalala !

Step-by-step explanation:
-70x^4 + 30x
= 10x(-7x^3 + 3)
ANSWER: 10x(-7x^3 + 3)
I think it’s -36, not 100% sure though
Let a be the number of adults which bought a ticket and c the number of children who bought a ticket. We can use the information given to assemble a system of equations.
Tickets cost 8 dollars for a, 1 dollar for c, and the total amount made is 100
8a + c = 100
The total of a and c is 30
a + c = 30
We can now subtract one equation from the other to use the elimination method to solve the system.
8a + c = 100
-(a + c = 30)
7a + 0 = 70
We can now solve for a.
7a = 70
a = 10
There were 10 adults who bought tickets. We can use this value as a known, plugging it into an equation to solve for the number of children.
a + c = 30
10 + c = 30
c = 20
So, the final answer is "20 children and 10 adults Equation 1: a + c = 30 Equation 2: 8a + c = 100".
