I believe it would be 40+1.75x is less than or equal to 60. The answer would be 11 or about 11 but it can’t be 12 it’s over 20.
A linear equation would be the best fit, but the last point (-1,-7) kinda messes it up. If the -7 would have been a -6 the line y=-2x-8 would fit perfectly.
The IQR is of this problem is 17 because the Q3 (32) - Q1 (15) = 17
Vertical angles are equal
2x + 40 = 8x - 32
40 + 32 = 8x - 2x
72 = 6x
72/6 = x
12 = x
2(12) + 40 = 24 + 40 = 64
8(12) - 32 = 96 - 32 = 64
so angle 1 is 64 and angle 2 is 64
Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
