Well sine you know that 9 students already read something 14-12=2 so only 2 students read both.
Hello!
![\large\boxed{x = 1}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bx%20%3D%201%7D)
-x - 3 = 2x - 6
Begin by adding x to both sides:
-x + x - 3 = 2x + x - 6
-3 = 3x - 6
Add 6 to both sides:
-3 + 6 = 3x - 6 + 6
3 = 3x
Divide both sides by 3:
3/3 = 3x/3
x = 1.
Answer:
60?
Step-by-step explanation:
4000/200 = 20
20 × 3 =60
Answer:
90°&89°=neither
63°&47°=neither also
61°&29°=complementary angles
Step-by-step explanation:
90+89=179, neither 180 or 90
63+47=110, neither 180 or 90
61+29=90 which is what complementary angles equal.
i hope this helps you out.
