Find the value of x for which the lines l and m are parallel. Choices are in the attachment.. (disregard the filled in answer)

umka21 [38]

<h3>Answer: Choice B) 13</h3>

You chose the correct answer.

======================================================

Explanation:

Lines M and L are only parallel if and only if the corresponding angles are congruent.

The angles 127 and (9x+10) degrees are corresponding angles. They are both on the same side of the transversal, and they are to the right of each parallel line.

Set the two angle expressions equal to one another. Solve for x

9x+10 = 127

9x = 127-10

9x = 117

x = 117/9

x = 13

Taminka received a raise in her hourly pay, from $13.50 to $14.99. Find the percent change. Round to the nearest percent.

polet [3.4K]

Answer:

$\% = 11\%$

Step-by-step explanation:

Given

$Initial = \$13.50$

$Final = \$14.99$

Required

Determine the percentage change

This is calculated as:

$\% = |\frac{Initial - Final}{Initial} * 100\%$

$\% = |\frac{13.50 - 14.99}{13.50}| * 100\%$

$\% = |\frac{-1.49}{13.50}| * 100\%$

$\% = \frac{1.49}{13.50} * 100\%$

$\% = \frac{1.49* 100\%}{13.50}$

$\% = \frac{149\%}{13.50}$

$\% = 11.037037037\%$

$\% = 11\%$

Hi, can someone help explain this. (Triangle similarity/10th grade)

scZoUnD [109]

This is one proportion that can be created from the given information $\frac{36}{24} = \frac{6x-6}{3x+7}$ .

You would then use cross product to solve it. Also reduce 36/24 to 3/2
3(3x + 7) = 2(6x - 6)
9x + 21 = 12x - 12
33 = 3x I subtracted 9x from both sides and added 12 to both sides
11 = x
