Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
5 * 10^9 * 2.3 * 10^7
= 5 * 2.3 * 10^9 * 10^7
= 11.5 * 10^16
= 1.15 * 10 * 10*16
= 1.15 * 10^17

Answer:
B. 
Step-by-step explanation:
{y = 2x - 3,5
{x -2y = −14
x - 2[2x - 3,5] = −14
x - 4x + 7 = −14
−3x + 7 = −14
- 7 - 7
__________
−3x = −21
___ ___
−3 −3
[Plug this back into both equations above to get the y-coordinate of 10,5]; 
* 10½ = 10,5
