How many solutions does x + 2x + 7 = 3x - 7

Mathematics
1 answer:
Alex17521 [72]3 years ago
3 0

Answer:

No solutions! :)

Step-by-step explanation:

To find the number of solutions in a problem we must solve it.

x+2x+7=3x-7

Firstly, combine common terms:

3x+7=3x-7

We can subtract 3x from both sides:

7=-7

The solution is 7=-7, which is no solution.

When a number is equal to a number in a solution, it has no solutions!

Answer:

13.82 in.

Step-by-step explanation:

To find the circumference of a circle, you multiply the diameter by pi (\pi):

(4.4)(\pi )=13.82301

Rounded to the nearest tenth, 13.82301 is 13.82. Therefore, 13.82 is the answer.

Answer:

1306.24 cm².

Step-by-step explanation:

From the diagram given above, we obtained the following information:

Radius (r) = 13 cm

Pi (π) = 3.14

Slant height (l) = 19 cm

Surface Area (SA) =.?

The surface area of the cone can be obtained as follow:

SA = πr² + πrl

SA = πr ( r + l)

SA = 3.14 × 13 ( 13 + 19)

SA = 40.82 (32)

SA= 1306.24 cm²

Therefore, the surface area of the cone is 1306.24 cm².

Answer:

Step-by-step explanation:

First you divide the total mulch (77 1/2) by the amount per bag (2 1/4). This will tell you how many bags of mulch you have.

The answer is 34.4444444 which is 34 full bags of mulch.

Now if one bag is $2.25, then what is 34 bags?

$2.25 multiplied by 34 is $76.5

Hope this helps your understanding
