Answer:
56
Step-by-step explanation:
The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).
The sum of a triangles' angles is 180 degrees.
Therefore 4v-44 = 180.
v - 11 = 45
v = 56 degrees

Answer:
1.
x=-10
x=-6
2.
x=10
x=-3
Step-by-step explanation:
to find the zeros of a function you need to set it equal to zero:
x^2+16x+60=0
then you factor
(x+10)(x+6)=0
then you have to finish factoring/simplifying
x+10=0
-10
x=-10
x+6=0
-6
x=-6
and the same thing for number 2
x^2-7x-30=0
(x-10)(x-3)=0
x=10, x=3
Put all numbers in order from least to greatest
median is the middle number
so
5,9,10,11,12,14
median = ( 10+11)/2 = 10.5
answer
C. 10.5
Answer
16
Explanation
4x+4=2x+36
-4. -4
4x=2x+32
-2x -2x
2x=32
x=16
Answer:
The price of one hot dog is $1.65
Step-by-step explanation:
8h+4c= x
c= 1.25
x= 18.20
8h + 4(1.25)= 18.20
8h + 5 = 18.20
( subtract 5 from both sides of the equation)
8h = 13.20
( divide both sides by 8 to isolate the variable)
h = 1.65
so each hot dog is 1.65
