Answer:
75
Step-by-step explanation:
All of the angles within the triangle must add up to 180 degrees. So, angle 2 =50
The angles 4,2,5 also equal 180 because they are on the blue line. Since angle 2=50 and angle 5= 55 angle 4 must be 75 which is needed to add up to 180.
A) 2x - 7 = -1
Add 7 to both sides of the equation.
2x = 6
x = 3
Choice A is not the answer.
B) 3x + 8 = 1
Subtract 8 from both sides.
3x = -7
Divide both sides by 3.
x = -2.3 repeating
Choice B is not the answer.
C) 1/2x + 8 = 10
1/2x = 2
Divide both sides by 1/2.
x = 4
Choice C is not the answer.
By process of elimination, choice D is the answer.
D) 1/2(2x - 6) = -6
x - 3 = -6
Add 3 to both sides.
x = -3

Answer:
24x
Step-by-step explanation:
The total length of all vertical segments is 5x·2 = 10x.
The total length of all horizontal segments is (3x+4x)·2 = 14x.
Then the total length of all perimeter segments is ...
10x +14x = 24x . . . . perimeter of the figure
F=2/3 of S
F+S=310
2/3 S + S = 310
(2S + 3S)/3=310
S=[(310)(3)]/5
S=186 students taking Spanish
F=2/3 of 186
F=124 students taking French
