You are supposed to mutipy the first two and then add it
The correct answer is 35. What are you trying to figure out?
Answer:
Step-by-step explanation:
7(a + 2b) + x(a + 2b)
(7 + x)(a + 2b)
The amount charged is an illustration of a linear equation.
Tina charges $39 for 4 hours
The given parameters are:
--- amount charged for the first hour
--- amount charged for the extra hours
If Tina babysits for 4 hours, it means that:
- <em>She will charge $15 for the first hour</em>
- <em>$8 for the extra 3 hours</em>
<em />
So, the total charges is:



The ordered pair is (4,39)
It means that:
She charges $39 for 4 hours

Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t
r = 20mi/24min
= 0.833333 mi/min.
d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
