Hello ,
-1/3 x + 15/3 = -4
-1/3 x + 5 = -4
-1/3 x = -4-5
-1/3 x = -9
x = -9 : -1/3
x = -9 * -3/1
x = 27 .
Answer:
∠A and ∠C are vertical and equal in measure
∠C is adjacent to the angle that is 27°
∠C and ∠B are supplementary
∠A and ∠B are supplementary AND adjacent
All of them are correct
Step-by-step explanation:
<u><em>This is just how to find the angles.</em></u>
"When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex." - MathPlanet
The 27° and the 90° angles added up equal ∠B
∠B = 117°
360°-117°-117°=∠A & ∠C
∠A + ∠C = 126°
∠A=∠C=63°
Answer:
(3,-2)
Step-by-step explanation:
Equal both equations 2/3 x-4=-2x+4
8/3 x=8
x =3
Input 3 into either original equation to find y
y=-2
Answer:
I think 85%
Step-by-step explanation:
I did butterfly method how I use to so i dont know if its right
For every 3 seconds, the scuba diver dives 0.5 feet
after 15 seconds = your answer
3 x 5 = 15
0.5 x 5 = your answer
your answer = 2.5
2.5 is your answer
hope this helps
