Answer:
Step-by-step explanation:
step 1
Find the value of w
we know that
---> by supplementary angles (form a linear pair)
substitute the given values
step 2
Find the measure of angle EPD
we know that
----> by vertical angles
substitute
substitute the value of w
step 3
Find the measure of arc DE
we know that
----> by central angle
therefore
Answer:
1st evening = 7 + 20 = 27 calls
2nd evening = 3 (20 ) = 60 call
3rd evening = 20 calls
Step-by-step explanation:
total calls for the last three evenings = 107 phone calls
2nd evening = 3x as many calls as the 3rd evening
1st evening = 7 more calls than the 3rd evening.
find:
how many calls did she receive each evening?
let T (total) = 107
let x = 3rd evening.
let 2nd = 3x
let 1st = (7 + x)
T = 1st + 2nd + 3rd
107 = (7 + x) + 3x + x
107 - 7 = 5x
100 = 5x
x = 100 / 5
x = 20
therefore,
1st evening = 7 + 20 = 27 calls
2nd evening = 3 (20 ) = 60 call
3rd evening = 20 calls
Answer:
4
Step-by-step explanation:
1/4 is a quarter at up 1/4 4 time and it gives you a whole, 1/4+1/4+1/4+1/4=1
Answer:
The x value that make least sense to use is -2.75
Step-by-step explanation:
As x is a value of time, it is senseless to have negative values because time is an escalar value then it goes in only one direction. This is why time can only be a positive value.
You just subtract the number
