1.Muliply parenthesis by 2
2x+2-4=4
2.calculate the difference
2x-2=4
3.move constant to the right side and change its sign
2x=4+2
4.add the numbers
2x=6
5. Divide both sides of the equation by 2
x=3

Answer:
Step-by-step explanation:
They are testing whether you remember the basic 30,60,90 degree triangle side relationship. The ratio of sides for this triangle are 1 opposite the 30 degree angle, square root of three opposite the 60 degree angle and a hypotenuse of 2 opposite the 90 degree angle.
x/2=2/1
x=4/1=4
bottom answer choice
x/4=3^(1/2)/1
x=4(3^(1/2))
third answer choice
Answer:
the first one.
Step-by-step explanation:
DJ and decorations are one time flat costs. they are constant. so, together, they are $300.
that is what decreases the profit.
on the other side, $5 per student = 5n in total increases our profit.
so, in total the sum of both (the decreasing amount has a negative sign, if course) :
5n - 300 = 1,500
is the right equation to calculate how many students are needed to make that much profit.
the solution, but the way :
5n - 300 = 1500
5n = 1800
n = 1800/5 = 360 students
Answer:
it will have to be 90 degrees, because two angles that are supplementary add up to be 180 degrees so 90 + 90 is 180. hope this helps
