Answer:
1 taco is $4
Step-by-step explanation:
2t + 3d = 14 4t + 6d = 28
3t + 2d = 16 -9t -6d = -48
-5t = -20
t = 4
The equations has the form:
c=mt, where m is the constant of proportionality
If we isolate m in the equation above:
c=mt
c/t=mt/t
c/t=m
m=c/t
m is c divided by t
If we take the values of the table, and divide c by its correspondent t, we get:
m=c/t=25.50/3=34.00/4=42.50/5=51.00/6=59.50/7→m=8.5
Then: c=8.5t
Answer: The equation that represents the proportional relationship in the table is: Second option
Answer:
4,140 degrees
Step-by-step explanation:
Mathematically, the sum of interior angles of a polygon is;
(n-2)180
where n is the number of sides the polygon has
Mathematically;
we will be replacing n by 25 here
So, we have;
(25-2)180
= 23 * 180 = 4,140 degrees
