Hint: Both are equal here

so x+6 = 2x+3 then solve for x

(a)

Hint: Here 5x+30 = 90

Now solve for x

(a)

Hint: Here 2(2x+7) = 3x+18

Now solve for x

(a)

Hint: Here take $\frac{20}{10\ }=\ \frac{50}{x}$

Now solve for x

(a)

Hint: $\frac{y\ -\ coefficient}{x\ -\ coefficient}$

(a)

A triangle has vertices at (1, 8), (-3, 4), and (1, 3).

Place the value that BEST completes the sentence.

The perimeter of the triangle is approximately ________ units.

Hint: Find the distance between all three points of all three sides and add them all

Two lines are represented by the equations $\frac{-1}{3}y\ =\ 5x\ +10$ and y = mx. For what value of m will the lines be parallel?

Hint: multiply the x - coefficient with the -3

Parallel Slopes are the same

Example: For the equation y=7x-4, the slope will be 7

(a)

Hint: Plug each value for n and check which answer satisfies the question

The formula to calculate the measure of an exterior angle = 360 ° ÷ number of sides = 360 ° /n

100

100n

$\frac{360}{n}$

$\frac{360\left(n-2\right)}{n}$

A regular Octagon is shown below.

Angle Q is 3x-57 degrees and angle M is 3x degrees.

Which statement explains why the equation 3x-57 = 3x can be used to solve for x?

Hint: Check which type of Octagon this is

A regular hexagon is defined as a closed 2D shape with six equal sides and six equal angles.

All polygons have congruent sides.

The sum of the interior angle measures of an octagon is 180 degrees

The value of 3x equals the sum of the interior angles of a regular octagon.

The interior angles of a regular octagon (or any regular polygon) are congruent.

10.

Hint: The ratio of circumference to its diameter will be π

and π is 3.14

The radius is always about 1/2 the circumference.

The ratio of the diameter to the circumference is always a little less than 2.9.

The ratio of the circumference to the diameter is always a little more than 3.

The circumference is always the radius times the diameter.

11.
