vlada-n [284]

Answer: The perimeter is 30ft.

Step-by-step explanation:

Let's define:

L = length of the longer side.

S = length of the shorter side.

P = perimeter

we know that for a common rectangle:

P = 2*S + 2*L

We aso know that:

L = 2ft + (1/3)*P

S = (1/10)*P

L = S + 9ft.

So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)

First, we can replace the third equation in the first equation, now we have a system with only two equations:

S + 9ft = 2ft + (1/3)*P

S = P/10

Now we can replace the second equation in the first equation, and get:

P/10 + 9ft = 2ft + P/3

Now let's solve this for P.

9ft - 2 ft = P/3 - P/10

7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)

(30/7)*7ft = P = 30ft.

The perimeter is 30ft.

Help with these twoo
Kobotan [32]

Answer:

g(N)=3 + 7n

80 = 3 + 7n

move the variable to the left hand side so

80 - 7n = 3

now do 3 - 80 to get -7n = -77

now divide both sides by -7 to get

n=11

2nd

p(x) = 4x

6= 4x

so swap the equations so its

4x = 6

next divide both sides by 4

x = 3/2 or 1.5
