Answer:
x=3,y=1
Step-by-step explanation:
2^x+y=16,3^x-y=9
16=2^4,9=3^2
x+y=4,x-y=2 add both
2x=6,x=3
3-y=2,y=1
Answer:
D
Step-by-step explanation:
Any set of three angles that add up to 180 degrees can form a triangle.
I believe that the answer is B) 60°.
Because the angle inside the circle equals 120°, and since these are 30°, 60°, 90° triangles, angles A and B are both 90°.
Which means that the remaining angles outside the circle each equal 30°.
Therefore, when both of these angles are added together, ∠T = 60°
Answer:
$181
Step-by-step explanation:
Multiply 30.75 by 12 because there are 12 months in one year.
30.75 x 12 = 369
Then subtrcact 369 from 550 to get the net change.
550 - 369 = 181
Michael is left with an account balance of $181.
