we do 2x-1/y=w+2/2z
2x-1/y we multiple each side y
2x-1/y×y=2x-1
then w+2/2z
we said×2z×2z
then we got
w+2
later
2x-1=w+2=
then 1 become another side
which is 1+2=3
then
w=3-2x
I hope it's correct
Answer:

Step-by-step explanation:
The diagram for the question is attached below
perimeter of the triangle is 28 feet
area of a square is 144 feet
Area of the square is side^2

take square root on both sides
side = 12
side of the square = 12
side is the diameter of the semicircle
Diameter = 12 , so radius = 12 divide 2 = 6
circumference of semicircle = 
one side of the rectangle is calculated in the perimeter of triangle and other side is calculated using circumference
perimeter of other two side = 2(12)= 24
Total perimeter =

i am just a little confused but so far its a yes
Step-by-step explanation:
4*3^2 = 36. Is that what you meant?
Answer:
Kindly check explanation
5 years from now, Johnathan will be (5 + 4) = 9 years
Step-by-step explanation:
Let Belinda's age = x
Jonathan's age =1/3 x
In 12 years, Belinda will be m years old :
Belinda's age now = x
Jonathan's age 5 years from now, if m = 36
Belinda's age in 12 years, Belinda's age = m
x + 12 = 36
x = 36 - 12
x = 24 years
Hence Belinda's age now is 24
Jonathan's age now is (1/3) * 12 = 4 years
Hence, 5 years from now, Johnathan will be (5 + 4) = 9 years
