Answer:
1.5
Step-by-step explanation:
4y + 11 = 17
-11 -11
4y = 6
/4 /4
1y = 1.5
City A is 25% less than population of city B. So city A's population is 75% of city B
<h3>
<u>Solution:</u></h3>
Given that City A is 25% less than population of city B
To find: city A's population is what % of city B
From given information,
City A is 25% less than population of city B
A = B - 25% of B
So we can write as,
A = 0.75B can be written as,
city A = 75 % of City B
Thus city A's population is 75% of city B
Dodecagon is a plane figure with 12 sides. To find the sum of angles of a dodecagon, we have to use the formula of sum of angles of a polygon with n sides, which is
S= (n-2)180
For Dodecagon , n=12. Therefore on substituting 12 for n , we will get
S= (12-2)180 =10*180 = 1800 degree .
SO the sum of angle measures of a dodecagon is 1800 degree .
Answer:
y = -1/2x - 7
Step-by-step explanation:
y2 - y1 / x2 - x1
-6 - (-5) / -2 - (-4)
-1 / 2
= -1/2
y = -1/2x + b
-5 = -1/2(-4) + b
-5 = 2 + b
-7 = b
The value of x is 5. Angle one and four are vertical. You can do this by writing 7x = 3x + 20. Isolate the variable by moving 3x to the other side. If you do this, 3x becomes negative, and you end up with 7x-3x = 20 --> 4x = 20.
x=5.
