Answer:
X = -9
Step-by-step explanation:
y = k X for some fixed number constant k.
-5 = k (15)
k = -5/15 = -1/3
So y = (-1/3)X
When y = 3 ---> 3 = (-1/3)X
X = -9
Answer:
2995
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
1000* 5.99% * 50
Answer:
I believe the answer may be x= 24.5 I'm not certain though
Step-by-step explanation:
The angles inside the triangle must all add up to 180 so we can subtract 80 from 180 to get 98. Now I'm assuming the two undefined angles are equal because of the two angle bisectors that create the second triangle. If I'm correct in assuming that them we can divided 98 by 2 to get 49 which would be the measurement of both bottom angles. Since there's a line bisecting both of them we would then cut that number in half to get 24.5. I hope this helped, I'm not fully certain of this answer though.
