7. Spiderman weighs 180 pounds. He can work out and gain
2 pounds a week. How many weeks, w, must he work out
until he weighs 226 pounds?
5?

Answer:

8x + 6

Step-by-step explanation:

1/2(16x + 2) + 5

(1/2 × 16x + 1/2 × 2) + 5

8x + 1 + 5

8x + 6

That should be the answer.

Answer:

2,160

Step-by-step explanation: since M is proportional to L^3 so when L=2 then L^3=8 so M=160 which means if L = 3

When L = 3, the value of M is 540. The relationship between M and L³ holds true.

When two variables, M and L, are directly proportional, it means that their ratio remains constant.

In this case, M is directly proportional to L³, which can be written as M = k × L³, where k is the constant of proportionality.

To find the value of k, we can use the given information when L = 2, and M = 160:

160 = k × 2³

160 = k × 8

k = 160 / 8

k = 20

Now that we have the value of k, we can find the value of M when L = 3:

M = 20 × 3³

M = 20 × 27

M = 540

So, when L = 3, the value of M is 540. The relationship between M and L³ holds true for any value of L when multiplied by the constant of proportionality k, which we found to be 20 in this case.

Eliminating y right away is easiest. Add -3(equation 1) to equation 2, and add 3(equation 3) to equation 2:

-3(2x + y + 3z) + (-3x + 3y - 2z) = -3(3) + (-8)

-6x - 3y - 9z - 3x + 3y - 2z = -9 - 8

-9x - 11z = -17

9x + 11z = 17   [equation 1]

3(5x - y + 5z) + (-3x + 3y - 2z) = 3(13) + (-8)

15x - 3y + 15z - 3x + 3y - 2z = 39 - 8

12x + 13z = 31   [equation 2]

Eliminating x next is easier than eliminating z. Add -4(equation 1) to 3(equation 2):

-4(9x + 11z) + 3(12x + 13z) = -4(17) + 3(31)

-36x - 44z + 36x + 39z = -68 + 93

-5z = 25

z = 25/(-5)

z = -5

Plug this into either of the previous equations and solve for x :

9x + 11z = 17

9x + 11(-5) = 17

9x - 55 = 17

9x = 72

x = 72/9

x = 8

Plug x and z into any of the 3 original equations and solve for y :

2x + y + 3z = 3

2(8) + y + 3(-5) = 3

16 + y - 15 = 3

1 + y = 3

y = 2

Formula

P = 2*w + 2*L

Area = L*w

Givens

Area = P

L = 6

Create equation and Solve

LW = 2w + 2L

6w = 2w + 2*6

6w = 2w + 12                    Subtract 2w from both sides

6w - 2w = 12                     Combine

4w = 12                             Divide by 4

4w/4 = 12/4          

w = 3
