Answer:
9
Step-by-step explanation:
4.20 / 4 = 1.05
105 x 9 = 9.45
Use point (-3,2):
2 = 4*(-3) + b
b = 2 +12
b = 14
The equation is y = 4x + 14

Answer:
<u>The regular polygon has 13 sides</u>
Correct statement and question:
If the sum of the measures of the interior angles of a polygon is 1980°, how many sides does it have?
Source:
1,920° is not a valid value for a regular polygon. It should be either 1,980° or 1,800° (it has to be a multiple of 180). We pick 1,980° to answer the question.
Step-by-step explanation:
Let's recall that the formula of the sum of the interior angles of any polygon is:
Sum of Interior Angles = (n-2) * 180°, where n is the number of sides of the polygon.
Therefore, replacing with the value we know:
1,980 = (n-2) * 180
n - 2 = 1,980/180
n - 2 = 11
<u>n = 13</u>
Answer:
C
Step-by-step explanation:
if you see the questions it shows you the letter of the number as you can see there are 2 y in an algebra format C is the only one with the letter of the algebra
have a great day ahead :)
Answer: 21 questions
Step-by-step explanation:
Turn it into a number sentence.
72% of x amount of questions is 15
0.72(x) = 15. Divide both sides by 0.72
x= 20.83333 round to nearest whole number
x= 21 questions
