Just work backwards.
342.5/ 34.25 = 10
First we write equation for perimeter of rectangle. Why? because we have been given that it is 128 units and maybe we can calculate something from it.
P = 2a + 2b where
a = 2(3y + 1 ) and b = 2(2y +3)
P = 6y + 2 + 4y + 6 = 10y + 8 = 128
now we can solve for y
10y = 120
y = 12
Now we just express value of y in formula for finding lenght of VW and we got length
Answer is 37
Answer:
The area of the room is 37.5 square inches.
Step-by-step explanation:
Consider that the room is rectangular in shape.
The dimensions of the rooms are:
Length (l) = 7.5 inches
Breadth (b) = 5 inches
The area of a rectangle is:
Area = l × b
Compute the area of the room as follows:
Area = l × b
Thus, the area of the room is 37.5 square inches.
Answer:
i dont know if you can see the whole thing but here is the answer
Step-by-step explanation:
15/x = 20/100
15*100 = 20*x
1500 = 20x
1500/20 = 20x/20
75 = x
15/75 = 20/100
the expected number of couples who met online is 75
