Answer:

8 =x

Step-by-step explanation:

2x+9=3x+1

Subtract 2x from each side

2x-2x+9=3x-2x+1

9 = x+1

Subtract 1 from each side

9-1 = x+1-1

8 =x

Answer:

x = 8

Step-by-step explanation:

2x + 9 = 3x + 1

Add -3x and -9 on both sides.

2x + 9 - 3x - 9= 3x + 1 - 3x - 9

2x - 3x = 1 - 9

Combine like terms.

-1x = -8

Divide both sides by -1.

-1/-1x = -8/-1

x = 8

(1 point) A chain 64 meters long whose mass is 24 kilograms is hanging over the edge of a tall building and does not touch the g
miss Akunina [59]

Answer:

W = 2747,1 [J]

Step-by-step explanation:

Chain is 64 meters long with mass 24 Kg

Then weight of the chain is p = 24 * 9.8

p = 235.2 [N]         N = kg*m/s²

And by meter is 235,2 / 64    = 3.675

Total work has two component

- work to lift the 13 top meters of chain  W₁

W₁ = ∫₀ᵇ F(y) dy

- work to lift last ( 64 - 13 ) meters  51   W₂

W₂ = 3.675 * 51 * 13      Kg m² /s²   [J]

W₂ =  2436,53 [J]

We need to calculate  W₁

W₁  = ∫¹³₀ mgy dy    ⇒     W₁  = ∫¹³₀ 3,675 ydy

W₁  = 3,675* ∫¹³₀ ydy     W₁  = 3,675* y²/2  |₀¹³

W₁  = 3,675* 84,5 [J]

W₁  = 310,54 [J]

And total work W

W = W₁ + W₂

W = 310,54  + 2436,53 [J]

W = 2747,1 [J]

Which table shows a proportional relationship between x and y?
oksano4ka [1.4K]
The top one. Think about the difference between each one: X goes from 1 to 2 and Y goes from 5 to 10. Each number you go up, Y increases by 5. This means there is a proportional relationship.

If we have 2 more blue pens than black pens, our blue pens can be rewritten as blue = 2 + black. Now we can set up an equation. Originally this equation would involve both blue and black, but since we only have 1 equation to set up, we can only have 1 unknown. That's why we base the number of blue pens on the number of black pens and do a substitution. So instead of blue + black = 94, we have (black + 2) + black = 94. That simplifies to 2 black + 2 = 94, and 2 black = 92. Now if we divide by 2, we get that the number of black pens is 46. If we have 2 more blue than black, the number of blue pens we have is 48. 46 + 48 = 94, so there you go!
