1/2 because there is 7 girls and 7 boys in total
Just a guess, but the angle inside the triangle that's not x or y is the remaining angle after subtracting the 30 degrees shown. That makes the non labeled angle inside the triangle 150 degrees. since all triangles are 180 degrees, this means x and y add up to 30. They look roughly the same, so i'd guess they're both 15 degrees.
Answer: D - 4 1/2 FT.
Step-by-step explanation:
36 (length of rope) divided by 8 (sections) equals 4.5
We can solve these equations by using substitution method where you substitute one equation to the other and solve for the value of the other variable. We do as follows:
y = 2x^2
y = –3x −1
2x^2 = –3x −1
2x^2 +3x +1 = 0
x1= -0.5
x2 = -1
y1 = 0.5
y2 = 2
The answer is A) P’(5,4)Q’(2,7)
hope this helped .
