Step-by-step explanation:
Let p1 be the perimeter of triangle ABC
p2 be the perimeter of triangle PQR
p1=(2x+4)+(2x+3)+(2x) = 6x+7
p2=(2x)+(2x)+(3x+1) = 7x+1
p1=p2 ⇔ 6x+7=7x+1 ⇔ 7x-6x=7-1 ⇔x=6
Then :
AC=2(6)=12
AB=2(6)+4=16
BC=2(6)+3=15
PQ=12
QR=12
PR=3(6)+1=19.

Answer:
If the number is 12 inches then the radius is probably 1.909859317 π inches
Answer:
138 pairs
Step-by-step explanation:
The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:
(eq1)
The number of gray non-pleated is twice the number of blue non-pleated slacks, so:
(eq2)
The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:
(eq3)
(eq4)
If we add (eq1) and (eq2), we have:
(eq5)
Using (eq3) and (eq4) in (eq5), we have:
From (eq1), we have:
From (eq3), we have:
Multiply $860 by .11 (11%) to find the answer.
$94.60 Is the interest earned.
This statment only works for linear systems because in non-linear systems it is okay to have more than one soultion
but if the system is linear than you can define it by it two soultions or in other words it takes two points to form a line and if two lines pass through the same points then you can define them by those point and they are the same line
