1. distribute 2 to x and 10 to get ride of parenthesis

2. subtract 2x from the left to move it to the right so x is by itself

3. add 15 to both sides to cancel it out on one side, and move to the other.

4. divide by 5 on both sides so you can get the value of x

5. flip equation so it is in the x equals form

1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.

2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)

3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left

4. divide by 6 on both sides of the equation to solve for x

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic

HACTEHA [7]

Hello,

x= number of points for each multiple choice question correct
L= Louann's score
C= Carla's score

Louann got 14 multiple choice questions correct and 24 points for her essay, so:

$L=14*x+24$

Carla got 16 multiple choice questions correct and 14 points for her essay, so:

$C=16*x+14$

But we know that they got the same score, then:

$L=C \\ 14x+24=16x+14 \\ 10=2x \\ \boxed{x=5}$

Answer: Each multiple choice question was 5 points

lozanna [386]

Answer:

19.5 miles

Step-by-step explanation:

The question is represented in the image attached.

∠A = 45°, ∠B = 45° + (216° - 180°) = 81°

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

45° + 81° + ∠C = 180°
