(Simplify your answer. Use a comma to separate answers as needed.)
Answer: x = 22
Step-by-step explanation:
Compare the 2 triangles
[tex]\frac{2x-8}{24} = \frac{45}{x+8}[/tex]
Cross multiply
(2x-8) (x+8) = 45 x 24
2x^2 + 16x - 8x - 64 = 1080
2x^2 + 8x - 64 - 1080 = 0
2x^2 + 8x - 1144 = 0 ---> divide by 2
x^2 + 4x - 572 = 0
(sum and product)
x^2 - 22x + 26x - 572 = 0
x(x - 22) + 26(x - 22) = 0
(x + 26) (x - 22) = 0
x + 26 = 0
x = -26
x - 22 = 0
x = 22

Complete the ordered pair so that it is a solution of 2/3x + y - 1 = 0. (-6, ___) 3 4 5
Answer:
(- 6, 5 )
Step-by-step explanation:
Substitute x = - 6 into the equation and solve for y
[tex]\frac{2}{3}[/tex] (- 6) + y - 1 = 0 , that is
- 4 + y - 1 = 0
y - 5 = 0 ( add 5 to both sides )
y = 5
Then solution is (- 6, 5 )

Answer:
pretty sure it's 65
Step-by-step explanation:
They're usually congruent for these type of angles. Also, y would be 50
Answer:
x = 50°
Step-by-step explanation:
y = 65° because the base angles of an isosceles triangle are equal
x = 50° because angles in a triangle add up 180°
65 + 65 = 130180 - 130 = 50°What is the median for this list of numbers? 11, 23, 43, 22, 9, 15

it takes two people to make two bikes in 2 hours how many people does it take to make 12 bikes in 6 hours
Answer:
Step-by-step explanation:
2 people make 2 bikes in 2 hours so 2 people can make 1 bike in 1 hour
So in 6 hours, 2 people can make 6 bikes.
So to make 12 bikes we need 2*2 = 4 people.

members of a softball team raised 1405.25 to go to a tournament. they rnted a bus for 822.50 and budgeted 27.75 per each players . write and solve an equation which can be used to determine x , the number of players the team can bring to the tournament
Creating an expression for the scenario, the Number of players that can be brought to the tournament is 21.
Given the Parameters :
Total amount raised = 1405.25Bus rent = 822.50Amount per player = 27.75We could represent the expression to calculate the number of players thus :
Total amount raised = (Bus rent + (amount per player × number of Players))
1405.25 = 822.50 + 27.75x
1405.25 - 822.50 = 27.75x
582.75 = 27.75x
x = (582.75÷27.75)
x = 21 players
Therefore, the Number of players would be 21.

Step-by-step explanation:
Answer:
-8(-4+x)
Step-by-step explanation:
This is because the value of all the numbers never changes. Because
"-8(x-4)= -8x+32" and "-8(-4+x)= 32-8x" are equal, this would be the only correct answer.

Find the value of X, rounded to the nearest tenth.
A. 31.8
B. 31.4
C. 10.3
D. 10.7
Answer:
B. 31.4
Step-by-step explanation:
To find x, the hypotenuse, we need to use sin because we have been given the opposite (the side opposite the angle 35°) and we need to work out the hypotenuse (the longest or slanted side):
SOH, CAH, TOA
sin(θ) = opposite ÷ hypotenuse
Sub in the values (we don't know the hypotenuse so i've called it x):
sin(35) = 18 ÷ x (multiply both sides by x)
x × sin(35) = 18 (divide both sides by sin(35))
x = 18 ÷ sin(35) = 31.38204...
x ≈ 31.4
Hope this helps!
