The step where the error occurred is Step 4. After step 3, 34x should've been added to both sides of the equation. Instead of -17x, Step 4 should say 17x, because -17+34=17. Somehow, the whole number in Step 4 also changes from 40 to 14. Nothing changed it, it should still be 40. Step 4 should be: 17x=40.

To continue solving, divide both sides by 17.

x should be 40/17 or 2 6/17.

I hope this helps :)

Until 2014, the mass of a kilogram was defined as exactly equal to the mass of a special

emmainna [20.7K]

Step-by-step explanation:

We have,

Diameter of cylinder, d = 39.2 mm

Radius, r = 19.6 cm

Height of the cylinder, h = 39.2 mm

It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :

$S=2\pi rh+2\pi r^2\\\\S=2\pi r(h+r)$

Putting all values we get :

$S=2\times\dfrac{22}{7}\times19.6\cdot(39.2+19.6)\\\\S=7244.16\ mm^2$

Black diamond ski resort charges $25 for ski rental and $10 an hour to ski. Bunny hill ski resort charges $50 for ski rentals an

aleksley [76]

Answer:

Five hours at both ski resorts cost the same

Step-by-step explanation:

Let x = hours Let y = cost

Black Diamonds Ski Resort: 25 + 10x = y

Bunny Hill: 50 + 5x = y

Since the cost should be equal, we can substitute for these two equations.

25 + 10x = 50 + 5x

Solve for x:

x = 5

Check: Plug in for x

Black Diamonds Ski Resort: 25 + 10(5) = 25 + 50 = $75

Bunny Hill: 50 + 5(5) = 50 + 25 = $75

The cost is the same, so we know that five hours has the same cost at both ski resorts.

I hope this is correct! Please mark me as brainliest if this is correct :3
