The magic triangle is D and S and T where D is over S and T so if D is over s and t u dived and if the question is looking for D you would multiply S and T so 8 is the S i'm guessing and 15 is the T so ur gonna be looking for D so D=120 S=Speed D=Distance and T=time
i hope i helped you good luck
Sense there's only a y, you'd assume y is 1 or 1y.
you'd make the 1 a negative 1 to get rid of the subtraction sign.
you'd add together the 2 ys making it 2y. then add -1 + 3, which would be 2.
so, the answer would be 2y + 2.
See picture for reply and solution steps.
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c
y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
1= 130 yards
2= 55 yards
3= 25
