Answer:

x=6

Step-by-step explanation:

You would want to simplify and isolate "x" by itself.

First step is to add the like terms on one side:

2x+x+2=5x-10 ---> 3x+2=5x-10

Next, subtract 2 from both sides to simply the expression.

3x+2=5x-10

-2 -2

=3x=5x-12

Subtract 5x from both sides as well to simplify:

3x=5x-12

-5 -5

=-2x=-12

Divide both sides by -2 to isolate the x by itself.

-2x=-12

/-2 /-2

x=6

A cylinder has a radius of 6 centimeters and a height of 18 centimeters. A smaller cylinder has linear dimensions that are one-t

vlabodo [156]

Answer:

the larger cyclinder has a surface area which is 9 times the surface area of the smaller cyclinder.

Step-by-step explanation:

Surface area of larger cyclinder

Radius = 6cm

Height = 18cm

A = 2πrh + 2πr^2

= 2*3.14*6*18 + 2*3.14*6^2

= 678.24 + 226.08

= 904.32 cm

Smaller cyclinder (1/3 of the larger cyclinder)

Radius = 2cm

Height = 6cm

A = 2πrh + 2πr^2

= 2*3.14*2*6 + 2*3.14*2^2

= 75.36 + 25.12

= 100.48 cm

Comparing the surface area of the larger cyclinder and the smaller cyclinder

= 904.32 cm / 100.48 cm

= 9

This means, the larger cyclinder has a surface area which is 9 times the surface area of the smaller cyclinder.

What is the probability of rolling an odd number _or_ a 4 in **two rolls** of a (fair) six-sided die? may require outside refere

Stolb23 [73]

On a cube there are 6 sides. There are three odd numbers and one 4, so the probability of rolling these numbers is 4/6 which is 2/3. To get the probability of it from two rolls, we multiply it by itself once because it is being rolled once more. 2/3 x 2/3 is 4/9, so the probability of rolling an odd number or four in two roles is 4/9.

A town has two sneaker factories, Sneakerheadz and Nukicks. While Nukicks was closed on Sunday, Sneakerheadz made 900 pairs of s

Scilla [17]

Answer:

Sneakerheadz produced 900 pairs on Sunday. And on Monday, they produced shoes at a rate of 300 per hour.

Then the total number of pairs produced is:

S(t) = 900 + 300*t

where t represents the number of hours worked on Monday.

We know that Nuckicks only worked on Monday, and the same amount of time as Sneakerheadz, but at a rate of 480 sneakers per hour.

We can write the total number of pairs as:

N(t) = 480*t

Now we know that Nukcicks produced in Monday the sane number of pairs than Sneakerheadz produced in the two days, then we have that:

S(t) = N(t)

900 + 300*t = 480*t

900 = 480*t - 300*t = 180*t

900/180 = t

5 = t

So the factories operated 5 hours on Monday.

el producto de tres números es 1000 y su suma es 39. Si se sabe que el primero es al segundo como el segundo es al tercero, hall

pentagon [3]

Answer: The difference between the larger and smaller number is 21.

Step-by-step explanation:

This can be translated to:

"the multiplication between 3 numbers is 1000 and the addition is 39.

If the first number is at the second like the second at the third, find the difference between the smaller and the larger number"

If A is the first number, B the second and C the third we have that:

A*B*C = 1000

A + C + B = 39

A/B = B/C

From the third equation we have that:

A*C = B*B

we can replace it in the first equation and get:

B*(A*C) = 1000

B*B*B = B^3 = 1000

$B = \sqrt[3]{1000} = 10$

So now we have the value of B.

Now we have the two equations:

A + 10 + C = 39

A*C = B*B = 10*10 = 100

We can isolate A in the first equation and get:

A = 39 - 10 - C = 29 - C

now we can replace it in the second equation:

(29 - C)*C = 100

29C - C^2 - 100 = 0

We need to find the roots of that equation, we can use the Bhaskara's function:

$C = \frac{-29 +- \sqrt{29^2 - 4*(-1)*(-100)} }{2*(-1)} = \frac{-29 +- 21}{-2}$

Where we have two possible values for C

C = (-29 - 21)/(-2) = 25

C = (-29 + 21)/(-2) = 4

Let's chose C = 4, because C is the smaller value. (A will take the other value)

Then we have:

A + B + C = 39

A + 10 + 4 = 39

A = 39 - 14 = 25

Then the difference between the larger and smaller number is:

A - C = 25 - 4 = 21
