Answer 1
Answer:
angle 127° = angle 1 (vertically opposite angles)
now we have all the angles for the triangle
angle x + angle 29° + 127° = 180° ( sum property of triangle)
angle x + 156° = 180°
Angle x = 180° - 156°
Therefore, angle x = 24°

Answers
Answer:
12.56
Step-by-step explanation:
To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.
Circumference of a semi circle = πd/2
Given
Diameter d = 8
π = 3.14
Substitute;
C = 3.14(8)/2
C = 3.14 * 4
C = 12.56
Hence the the length of the arc is 12.56
8x-6y=-24
-48x+6y=144
Answers
8x−6y=−24
Step 1: Add 6y to both sides.
8x−6y+6y=−24+6y
8x=6y−24
Step 2: Divide both sides by 8.
[tex]\frac{8x}{8}[/tex] = [tex]\frac{6y-24 }{8}[/tex]
x= [tex]\frac{3}{4} y[/tex] [tex]-3[/tex]
---------------------------------------------------------------------------------------------
−48+6y=144
Step 1: Simplify both sides of the equation.
6y−48=144
Step 2: Add 48 to both sides.
6y−48+48=144+48
6y=192
Step 3: Divide both sides by 6.
[tex]\frac{6y}{6}[/tex] = [tex]\frac{192}{6}[/tex]
y = 32
Which property is shown in this example?
(6.3 + 5.2) + 8.7 = 6.3 + (5.2 + 8.7)
A. Identity Property
B. Commutative Property
C. Associative Property
D. Distributive Property
Answers
Answer:
associative property
Step-by-step explanation:
identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged. and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)

HERE is the riddle!!
Answers
Answer:
Prancer spent 240$
Dasher spent 120$
Cupid spent 360$
Step-by-step explanation:
Dasher = D
Prancer = P
Cupid = C
"Dasher spent half as much as Prancer"
D = 1/2P
"Cupid spent 3 times more than Dasher"
C = 3 * D
C = 3 * 1/2P
P + c + d = 720
P + 1/2p + 3*1/2P = 720
3P = 720
3P/3 = 720/3
P = 720/3
P = 240
Prancer spent 240$
Dasher spent 120$ (240/2)
Cupid spent 360$ (120*3)
Answer:
Dasher spent $120, Prancer spent $240, and Cupid spent $360

Choose a method (Elimination or Substitution) to solve the system of equations. Solve and explain your process.
Answers
Answer:
(x , y) = (1/22 , 4/11)
Step-by-step explanation:
{2x - 3y = -1
{15x (-2x) + y = -1 you write as a system of equations and then you simplify the expression which would be
{2x - 3y = -1
{- 30x + y = -1 and then you multiple both sides by 15 30x - 45y = 15 { -30x +y = -1 then you divide noth sides of the equation and then you substitute the vaul of y then you solve the equation check the solution nd then get your answer
