Answer:
2x - 2y = -8
x + 2y = -1
3x = -9
x = -3
-3 + 2y = -1
2y = 2
y = 1
(-3, 1) is the solution
Step-by-step explanation:
Answer:


Step-by-step explanation:
We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.
To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.
, where r represents radius of the circle.



Therefore, the exact area of the side walk is 
To find the approximate area of side walk let us substitute pi equals 3.14.


Therefore, the approximate area of the side walk is
.
Answer:
the answer for this question is 15/14
to find area the formula is area = l×b
here length is 1 1/4 and breadth is 3/4 so l×b = 1 1/4=5/4 so 5/4×3/4=15/14
The percentage of votes claimed by Adam is 53.62 %
<em><u>Solution:</u></em>
Given that, 5000 people went to vote
Candidate Smith claimed 52% of the votes. Candidate Adams claimed 2681 votes
To find: Percentage claimed by Adam
From given,
Total number of votes = 5000
Votes claimed by Adam = 2681
<em><u>The formula used is:</u></em>

<em><u>Substituting the values we get,</u></em>

Thus percentage of votes claimed by Adam is 53.62 %
