Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
Deacon Middle School
5x = number of boys
4x = number of girls
where x is some unknown number for now
(number of boys)+(number of girls) = 270 students total
5x+4x = 270
9x = 270
x = 270/9
x = 30
Since x = 30, this means
number of girls = 4x
number of girls = 4*30
number of girls = 120
There are 120 girls at Deacon Middle School
-----------------------------------------
Similarly, for Meadow Middle school
number of boys = 4y
number of girls = 5y
for some number y
(number of boys) + (number of girls) = 180 students total
4y+5y = 180
9y = 180
y = 180/9
y = 20
making,
number of girls = 5*y
number of girls = 5*20
number of girls = 100
so there are 100 girls at Meadow Middle School
-----------------------------------------
In summary so far, there are...
120 girls at Deacon Middle School
100 girls at Meadow Middle School
In total 120+100 = 220 girls from both schools
This is out of 270+180 = 450 students total
Divide the two values (220 and 450) to get
220/450 = 22/45
The final answer is 22/45
It cannot be reduced further as there are no common factors (other than 1) between 22 and 45

They are equal
Answer: A (10,-6)
Step-by-step explanation:
<u>step 1</u>:- The equation of the circle is given center and radius is
<u>Step 2</u>:-
A circle has its center at (6,-3) and point on the circle is (3,1),Now
we have find radius from center to the given point on the circle
The distance of two points are
<u>step 3</u>:-
The equation of the circle having center and radius is
verification:
This circle is passing through the point (10,-6)
There fore the another point that lies on the circle is (10,-6).
