Now we need to find


Answer:
Hamadi : -13-30x
Carlos : 5(7+6x)
Step-by-step explanation:
When we simplify Hamadi :
11-30x-24=
-13-30x We cannot simplify and nothing to do any more.
When we simplify Carlos :
11+30x+24=
35+30x
Common factor is 5:
5(7+6x)
Answer:
c = 4(d) + .43(m)
Step-by-step explanation:
We can test this by plugging in numbers for each of the variables. Let's say Jamal drove 5 miles over 2 days.
c = 4(2) + .43(5)
c = 8 + 2.15
c = $10.15
Have a nice day!
