Answer:

From the previous step you can see that both had an AC in common so that was factored out. The missing reason is Distributive Property

No, you would use two circles, one for each base, and one rectangle for the sides.

Answer:

either a ratio 8;7. or a percentage of 53% for picking the blue marble first i think and a 50/50 chance if you keep that blue marble out.

J=(7x+13) K=(83-2x) and the sum of the measures of the angles is 141. What is the measure of each angle

natta225 [31]

Answer:

j=76 and k=65

Step-by-step explanation:

$j + k = 141 \\ 7x + 13 + 83 + - 2x = 141 \\ 96 + 5x = 141 \\ 5x = 141 - 96 \\ 5x = 45 \\ x = \frac{45}{5} \\ x = 9 \\ j = (7 \times 9 + 13) \\ j =76 \\ k = 83 - 2(9) \\ = 83 - 18 \\ = 65$

NO LINKS! Please help me with this problem

Viktor [21]

Answer:

x=70, y=55

Step-by-step explanation:

Since the angle "y" and 2x-15 form a straight line, that means the sum of the angles, must be 180 degrees.

So using this we can derive the equation: $y+2x-15=180$

The next thing you need to know is that the sum of interior angles of a triangle is 180 degrees, so if we add all the angles, we should get 180.

So using these we can derive the equation: $x+2y=180$

So, in this case we simply have a systems of equations. We can solve this by solving for x in the second equation (sum of interior angles), and plug that into the first equation.

Original Equation:

$x+2y = 180$

Subtract 2y from both sides

$x = 180-2y$

Now let's plug this into the first equation

$y+2x-15=180$

Plug in 180-2y as x

$y+2(180-2y)-15=180$

Distribute the 2

$y+360-4y-15=180$

Combine like terms

$-3y + 345 = 180$

Subtract 345 from both sides

$-3y = -165$

Divide both sides by -3

$y=55$

So we can plug this into either equation to solve for x

$x+2y=180$

Substitute in 55 as y

$x+2(55)=180$

$x+110=180$

Subtract 110 from both sides

$x=70$

C is the midpoint of segment AD. B is the midpoint of segment AC. BC = 12. What is the length of segment AD? *

guapka [62]

Answer:

Step-by-step explanation:

A - B - C - - - D

12 + 12 + 24 = 48

Segment B is midpoint between AC therefore the length between AB is equal to the length between BC. C is midpoint of of AD therefore the length between AB + BC is equal to the length between CD. IF AB is 12 then AB is 12. AC will be 24. Since CD is equal to AD, CD must also be 24. AD is distance AC plus CD = 48.
