Answer:
angle c = <u>83</u> degrees
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral add up to 180 degrees.
According to the rule, <D and <B add up to 180° and same for <A and C.
This means that the sum of (x + 100) and (3x) equal 180.
Therefore (x + 100) + (3x) = 180 →
4x + 100 = 180
–100 –100
4x = 80
÷4 ÷4
x = 20.
Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.
Since <A + <C = 180.
97 + <C = 180 → 97 + <C = 180
–97 –97
<C = 180 – 97 = 83°
7 + c = -10
First, subtract 7 from both sides. / Your problem should look like: c = -10 - 7
Second, simplify -10 - 7 to -17. / Your problem should look like: c = -17
Answer: c = -17
Well, first, let's label the variables for our equation:
240 Miles per day
Traveled for 4 days
_________________________________________
Now, let's set up an equation to help us:
240x = ?
Since they're trying to figure out how many miles the family traveled after 4 days, and, they're going 240 miles each day, we should plug in a 4 where 'x' is:
240 ( 4 ) = ?
Now, we multiply:
240
× 4
________
800
+ 160
________
960
Answer: The family traveled 960 miles in 4 days.

I am srry I don’t understand any of that
To find an average or "mean" add all numbers together, then divide by total numbers added together.
10150+10211+10424+10769+10884+11155+11477=75070
75070 ÷ 7 = 10724.28571
(the average distance is the answer above)
