False because parentheses go first.... just follow PEMDAS
11 is 110 for x and y
12 is 90 degrees for x and y
13 is also 90 degrees for x and y

5x + 3 = 10x + -17
Reorder the terms:
3 + 5x = 10x + -17
Reorder the terms:
3 + 5x = -17 + 10x
Solving
3 + 5x = -17 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
3 + 5x + -10x = -17 + 10x + -10x
Combine like terms: 5x + -10x = -5x
3 + -5x = -17 + 10x + -10x
Combine like terms: 10x + -10x = 0
3 + -5x = -17 + 0
3 + -5x = -17
Add '-3' to each side of the equation.
3 + -3 + -5x = -17 + -3
Combine like terms: 3 + -3 = 0
0 + -5x = -17 + -3
-5x = -17 + -3
Combine like terms: -17 + -3 = -20
-5x = -20
Divide each side by '-5'.
x = 4

Answer:
B
Step-by-step explanation:
count how many x^2 there are because they would tell you what your answer is.
Okay dso if she got 15 points for 12 days then you would multiply them (or just add 15+15+15+15 and so on but multiplying is easier) then you are going to add 55 because of the thirteenth day.
15(12)=180
180+55=235 is how many you have.
now you are going to subtract 500 from that number to see how many more you need. :)
