AB, CD and EF are straight lines. AB is parallel to CD. Work out the size of angle y
mylen [45]

Answer: 28

Step-by-step explanation:

Simplifying

2x + 16 = 3x + -12

Reorder the terms:

16 + 2x = 3x + -12

Reorder the terms:

16 + 2x = -12 + 3x

Solving

16 + 2x = -12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

16 + 2x + -3x = -12 + 3x + -3x

Combine like terms: 2x + -3x = -1x

16 + -1x = -12 + 3x + -3x

Combine like terms: 3x + -3x = 0

16 + -1x = -12 + 0

16 + -1x = -12

Add '-16' to each side of the equation.

16 + -16 + -1x = -12 + -16

Combine like terms: 16 + -16 = 0

0 + -1x = -12 + -16

-1x = -12 + -16

Combine like terms: -12 + -16 = -28

-1x = -28

Divide each side by '-1'.

x = 28

Simplifying

x = 28

A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again
bixtya [17]

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

hope that helps

Find the scale factor where the pre-image is the small triangle and the image is the large triangle.
allsm [11]

Scale factor is the ratio of two corresponding sides.

Here we have two triangles, where the preimage is the smaller triangle and the image is the larger triangle.

So scale factor =14/18 = 7/9

And to find the missing variable, we need to set the ratio.

7/9 = 28/x

Cross multiplying both sides

7x = 28*9

x = 36
