8 is b because a circle is 360.
Answer: × = 8
Step-by-step explanation:
-2 (3 x - 9 ) + 5x = 10
Step 1: Open the bracket
-6× + 18 + 5x = 10
Step 2: Combine like terms
-6× + 5× = 10 -18
-1× = -8
×= -8/-1
×=8
-7a + 5a < -(7-a) -(2a +1) Turns to
-7a +5a < -7 +a -2a -1 Which turns to
-2a < -1a -8 Which turns to
-1a < -8 Which turns to
1a > 8
