Step-by-step explanation:
P = 5x+2y
P = 5(3)+2(5) = 15+10 = 25 meters
x = 3/25 ×32 = 96/25 = 3.84 meters
y = 5/25 × 32 = 6.4 meters
<span>2x-5y=-6
8x+3y=68
|x y +1|
|2 -5 6| = 0
|8 3 -68|
DET = 6+40 = 46
x*DET = 340-18
x = 7
-y*DET = -136-48
y = 4

Answer:
A, D
Step-by-step explanation:
When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.
You could drop the 00 in 600 and divide 6 by 3. You will get 2.
Add the 00 and your answer is 200.
Check your answer by doing 200 x 3 which equals 600.
