Answer:
x=44
Step-by-step explanation:
By the exterior angle theorem, we know that
x+4+82=3x-2
simplify
x+86=3x-2
subtract x from both sides
86=2x-2
add 2 to both sides
88=2x
divide 2 from both sides
44=x
11-19m=-16m-16
move -16m to the other side
sign changes from -16m to +16m
11-19m+16m =-16m+16m-16 ( combine like terms)
11-19m+16m=-16
11-3m=-16
move 11 to the other side
sign changes from +11 to -11
11-11-3m=-16-11
-3m=-16-11
-3m=-27
divide both sides by -3 to get +m and by itself
-3m/-3=-27/-3
m=9
Check solution by using substitution method
11-19m=-16m-16
11-19(9)=-16(9)-16
11-171=-144-16
-160=-160
Answer:
m=9
total income= 2R-C-2P
R= omoun tof rent paid by each tenant = $700
C= cable bill = $100
P = Phone bill = $50
Replace the values:
Total income = 2(700)-100-2(50)
total income= 1,400-100-100 = 1,400-200= $1,200
Total income =$1,200
Hello :
625^1/4=((625)^1/2)^1/2 =√(√625) = √25 =5 because : √625 = 25
180-65=3x-10+2x
180-65+10=3x+2x
125=5×
25=x
AngleB= 3•25-10=65
AngleC= 2•25=50
