Solve for X If you have 2x+3

Mathematics
1 answer:
daser333 [38]3 years ago
5 0

Answer:

in the explanation

Step-by-step explanation:

According to the triangle midsegment theorem (if these points are midpoints),

2x + 3 is two times longer than 7, meaning it's 14.

2x+3=14

2x=11

x = 11/2

If there is an option for not enough info given, that should be right as it doesn't actually say that they are midpoints

a movie theater earns $3946 by selling 428 tickets. if a full price costs $10.25 and a discount costs $8, how many full price ti
kherson [118]
We need a system of equations here, one equation based on the NUMBER of tickets sold and another based on the MONEY earned by the sales.  We have 2 different types of tickets:  full price (f) and discount (d).  The total number of tickets sold is 428; therefore, the first equation is f + d = 428.  That accounts for the number of tickets sold.  Each full price is 10.25 which can be represented as 10.25f, and each discount ticket costs 8 which can be represented as 8d.  The money earned by selling these tickets at those prices was 3946.  That means that the second equation is 10.25f + 8d = 3946.  We will solve the first bolded equation for f to get f = 428 - d.  Sub that value in for f in the second bolded equation:  10.25(428-d) + 8d = 3946.  Distribute to get 4387 - 10.25d + 8d = 3946.  Combine like terms to get -2.25d = -441.  Solving for d we get 196.  That means that there were 196 discounted tickets sold.  Put that in for d in the first bolded equation to find the number of full price tickets.  f + 196 = 428,  and f = 232.  There were 232 full price tickets sold.  There you go!

In parallelogram ABCD , diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E, BE=2x2−x , and DE=x2+6 .
kondaur [170]
<span>The diagonals of a parallelogram bisect each other. So we just equate the two equations BE and DE 2x^2 - x = x^2 + 6 2x^2 - x - x^2 - 6 = 0 x^2 - x - 6 = 0 This is quadratic eqn. So we obtain. (x - 3) ( x + 2) = 0 Setting each to 0 and solving for x, we have that x = 3 and x = -2 So we have two possible values for BD. But Since BE = DE then we can simply double each If x = 3 BD = 2 (2(3)^2 - 3) = 2 ( 18 - 3) = 30 units If x = - 2 BD = 2((-2)^2 -3 ) = 2 (8 - 3) = 10 units</span>

Find x. Round your answer to the nearest tenth of a degree.<br> x
NeTakaya

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = \frac{adjacent}{hypotenuse} = \frac{6}{9} , then

x = cos^{-1} ( \frac{6}{9} ) ≈ 48.2° ( to the nearest tenth )
