I hope someone can help me here please don't answer nonsense!​
Wittaler [7]

Answer:

  282°

Step-by-step explanation:

The measure of long arc KLM can be found by first determining the measure of short arc KM. That arc can be found using the inscribed angle theorem.

__

<h3>value of x</h3>

The inscribed angle theorem tells you the measure of arc KM is twice the measure of the inscribed angle KLM that subtends it. This relation can be used to find the value of x, hence the measure of the arc.

  2∠KLM = arc KM

  2(5x -1) = 8x +14

  10x -2 = 8x +14 . . . . . . eliminate parentheses

  2x = 16 . . . . . . . . . . add 2-8x

  x = 8 . . . . . . . . . divide by 2

<h3>measure of arc KM</h3>

The expression for the measure of arc KM can be evaluated.

  arc KM = 8x +14 = 8(8) +14 = 78°

<h3>measure of arc KLM</h3>

The total of arcs of a circle is 360°, so the measure of long arc KLM will bring the total with arc KM to 360°:

  arc KM +arc KLM = 360°

  arc KLM = 360° -arc KM

  arc KLM = 360° -78° = 282°

The measure are long arc KLM is 282°.

Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on
IrinaVladis [17]

Answer:

Oil changes = 5

Vincent = 10 oil changes

Warren = 10 oil changes

Step-by-step explanation:

Vincent = 5 + h

Warren = 2h

Where,

h = number of oil changes

How long will that take?

Vincent = Warren

5 + h = 2h

5 = 2h - h

5 = h

h = 5

Number of oil changes = 5

How many oil changes will Vincent and Warren each have done?

Vincent = 5 + h

= 5 + 5

= 10 oil changes

Warren = 2h

= 2(5)

= 10 oil changes

When solving an equation, Tina gets to the last of line of her work and is left with "7=7." What does this mean?
jarptica [38.1K]

Answer:

B , there are infinite solutions.

Step-by-step explanation:

If you end an equation with a true statement, such as 0 = 0, then any value of the variable(s) you are solving for will satisfy the equation. This means that there are infinite solutions.
