Lets say y is number of adult tickets and x is number of student tickets
x+y=348
2x+y=348
(2x since I know that the student tickets are twice as much as adult tickets)
I now know that that student tickets make up 2/3 of the total number of tickets and 1/3 make up the number of adults tickets. So...
1/3 x 348= 116 adult tickets
2/3 x 348=232 student tickets
2(3x+7)+x=70
mutiply the bracket by 2
(2)(3x)(2)(7)+x= 70
6x+14+x= 70
6x+x+14= 70 ( combine like terms)
7x+14= 70
move 14 to the other side
sign changes from +14 to -14
7x+14-14=70-14
7x= 56
divide both sides by 7
7x/7= 56/7
x=8
Answer: x= 8
Step-by-step explanation:
Add 9 to both sides of the equation.
if you want to create a trinomial square on the left, find value that is equal to the square of half of b
Add the term to each side of the equation
SIMPLIFY >:(
How to Simplify it:
-Raise the -2 to the power of 2
and ten simplify 9 + (-2)^2 :
--Raise -2 to the power of 2 and then add 9 and 4
Factor the perfect trinomial square into (x - 2)^2
Solve the equation for x
How to do it:
-Take the square root of each side of the equation to set up the solution for x
--Then remove the perfect root factor, x - 2 under the radical to solve for x
---Remove parenthesis
----add 2 to both sides of the equation.
the final answer could be shown in different ways,but the exact form is x=±√13+2
In decimal form its x=5.60555127…,−1.60555127…
--this took me like 7 minutes to do im no geek tho lol
Answer:-11
Step-by-step explanation: add -4 to both sides which gives you -11.
