x = 5
Step-by-step explanation:
3x + 10x =65
13x = 65
/13 /13

x = 5
Answer:
1.6 Miles every hour
Step-by-step explanation:
6.4m÷4h=1.6m every h
Easiest way is to find which one is smaller
-2 is smaller than 6
8 is smaler than 10
so (-2,8) is smaller
we find the distance betewen them
distance between -2 and 6 is 8
distance beteeen 8 and 10=2
so
we add 1/2 of each to the smaller one
8/2=4
-2+4=2
2/2=1
8+1=9
the midpoint is (1,9)
Answer: Choice A) $0.45
================================
Explanation:
Plug in d = 0 and you'll have A(d) = 0.45d+180 turn into A(0) = 180. This says that Terry is paid $180 even if he doesnt travel a single mile.
Now plug in d = 1. You should get A(1) = 180.45 as the result.
Subtract the results: 180.45 - 180 = 0.45
He has earned 45 cents or 0.45 dollars for traveling one mile
----------
A shortcut is to notice that the slope of the line is 0.45
It might help to view A(d) = 0.45d+180 as y = 0.45x+180. We see that the equation is in slope intercept form y = mx+b
m = slope = 0.45 tells us how much additional dollars Terry earns for each additional mile traveled
b = 180 = y intercept = starting amount of money Terry is paid, this amount does not change based on how many miles he travels.
7/16*4/3*1/2=28/96=7/24 by simply multiplying and then simplifying the fraction.
