Answer:
6
Step-by-step explanation:
Rachel's cost = $35x + $15
Taylor's cost = $25x + $75
When are the costs equal? Rachel's cost = Taylor's cost?
35x + 15 = 25x + 75
35x - 25x = 75 - 15
10x = 60
x = 6
Check Rachel's 6 month cost is: 35 x 6 + 15 = 225
Check Taylor's 6 month cost is 25 x 6 + 75 = 225
Answer:
length = 20 mt
Width = 16 mt
Step-by-step explanation:
Let the length of the field be x
width of the field be y
Hence formula of the perimeter is given as
P=2(x+y)
P=72(given)
72=2(x+y)
Dividing both sides by 2 we get
x+y=36---(A)
Also given that width of the parallelogram is 4 meters less than its length
Hence
y=x-4
or x-y=4 ---(B)
Adding A and B
2x=40
x=20
y=x-4
y=20-4=16
Hence length = 20 mt
Width = 16 mt

Answer:
5x-8y
Step-by-step explanation:
4x-9y+x+y
=4x+-9y+x+y
=4x+-9y+x+y
=(4x+x)+(-9y+y)
=5x+-8y
=5x-8y
