All you do is make 3/4 into 12/16 and 12 is your answer.
Answer:
-6
Step-by-step explanation:
3b-5a 2a-6/2
3(2)-5(3) 2(3)-6/2
6-15 6-3
-9 + 3
=
-6
16 - 5(3t - 4) = 8(-2t + 11) <em>use distributive property</em>: <em>a(b + c) = ab + ac</em>
16 - (5)(3t) - (5)(-4) = (8)(-2t) + (8)(11)
16 - 15t + 20 = -16t + 88
36 - 15t = -16t + 88 <em>subtract 36 from both sides</em>
-15t = -16t + 52 <em>add 16t to both sides</em>
t = 52
