Answer:
-117
Step-by-step explanation:
x = 106 x 4 - (99+120+103+111+108)
x = 424 - 541
x = -117
Hope that helps!
Answer:

Step-by-step explanation:
Find common difference from subtracting any term in the sequence with the previous term.

Apply nth term formula.





Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
X/5= 15
So we gotta get x alone sooo
Since it’s division we do reverse and do multiplication for the answer
So 15 times 5 is 75
X = 75
(40x/64y)/(5x/8y)
(40x/64y)(8y/5x)
320xy/(320xy)
