A. 3a b. a^3 c. 4x d. 3pq e. 7^ef f. zxy^1
Answer:
The answer should be C) 4x + 5x = 180
Step-by-step explanation:
4a + 6b = 10
2a - 4b = 12...multiply by -2
----------------
4a + 6b = 10
-4a + 8b = - 24 (result of multiplying by -2)
------------------add
14b = - 14
b = -14/14
b = -1
2a - 4b = 12
2a - 4(-1) = 12
2a + 4 = 12
2a = 12 - 4
2a = 8
a = 8/2
a = 4
so 12a = 12(4) = 48 <==
5/10 bc it is equal to 1/2 which is bigger than 2/5 or 4/10 1/3
