So we simplify this and do
5(3a-1)-2(3a+2)=3(a+2)+v
15a-5-6a-4=3a+6+v
add like terms
9a-9=3a+6+v
subtract 6 from both sides and get
9a-15=3a+v
subtract 3a from both sides and get
6a-15=v or 3(2a-5)
so the answers are D,E
or if you want to avoid doing allot of math, you could just figure out which two answer choices are the same (D,E)
Answer:
s inversely proportional 1/t
s=0.3, t=8
s=k/t
0.3=k/8
k=0.3×8
k=2.4
find s when t=0.4
s=2.4/0.4
s=6.0 or 6
Answer: change in y over Change in x(slope)
2. 3/3 or 1
4. 5/4
6.4/5
8.1/4
10.-2/-3
12.1/-3
14.-9/9 or -1
He would pay $14. Each juice bottle costs $2, so 7 bottles cost $14.
First, subtract 30x from each side to get:
-60 = -10x
Then, divide each side by -10 to get:
x = 6
Now, plug back in to check your answer:
30(6) - 60 = 20(6)
180 - 60 = 120
120 = 120
Hope this helps!! :)
