An inscribed angle is an angle formed by two radii that share an endpoint A) True
B)False

Answers

check the picture below.

notice, as from the left, we grab those two angles and slap them together on the right, they form a wide angle A, and a smaller inscribed angle B.

now, the blue and red segments that came together, are both making up the inscribed angle B, and also sharing the side or endpoint, in the middle of angle A.

2.8y + 6 + 0.2y = 5y – 14

Answers

Answer:

y = 10

Step-by-step explanation:

Simplifying

2.8y + 6 + 0.2y = 5y + -14

Reorder the terms:

6 + 2.8y + 0.2y = 5y + -14

Combine like terms: 2.8y + 0.2y = 3y

6 + 3y = 5y + -14

Reorder the terms:

6 + 3y = -14 + 5y

Solving

6 + 3y = -14 + 5y

Solving for variable 'y'.

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

Add '-5y' to each side of the equation.

6 + 3y + -5y = -14 + 5y + -5y

Combine like terms: 3y + -5y = -2y

6 + -2y = -14 + 5y + -5y

Combine like terms: 5y + -5y = 0

6 + -2y = -14 + 0

6 + -2y = -14

Add '-6' to each side of the equation.

6 + -6 + -2y = -14 + -6

Combine like terms: 6 + -6 = 0

0 + -2y = -14 + -6

-2y = -14 + -6

Combine like terms: -14 + -6 = -20

-2y = -20

Divide each side by '-2'.

y = 10

Simplifying

y = 10

Answer:

y= 11

Step-by-step explanation:

we have:

2.8y + 6 + 0.2y = 5y – 14

or 3y + 6 = 5y -14

and 3y + 6 - 6 = 5y -16 -6

and 3y = 5y -22

and 3y - 5y = -5y +5y -22

so -2y = -22

finally y = -22/-2

or y=11
