Answer:
See below.
Step-by-step explanation:
The 3 marked angles add up to 360 degrees.
5x + 12 + 10x - 37 + 9x + 1 = 360
24x - 24 = 360
24x = 384
x = 384/24 = 16
The large angle at C = 10(16) - 37
= 160 - 37 = 123 degrees.
So m <BCA = 180 - 123
= 57 degrees (adjacent angles add up to 180).
Answer:
p=-2
Step-by-step explanation:
we can solve by both methods
if it is divisible by x-1,then remainder is zero.
i solve by synthetic division.
x-1=0,x=1
1 | 1 -1 p 2
| 1 0 p
_________
1 0 p |2+p
Here 2+p is remainder.
p+2=0
p=-2
Answer:
3
Step-by-step explanation:
first you add 10+2 then subtract 5 from the 12. then you multiply 6 and 2 that equals 12. now you minus 8 and 4 that equals 4. now you divide 12 and 4. that equals 3.
Answer: 140%
Step-by-step explanation:
STEP 1: FIND THE CHANGE IN # OF PEOPLE:
initial # of people: 144
final # of people: 346
change in # of people = (final - initial)
change in # of people = (346 - 144)
change in # of people = 202
STEP 2: FIND THE % CHANGE
202/144 = x/100
(100)(202/144) = x
100(1.4) = x
140% = x
