SIZIF [17.4K]

Answer:

4

Step-by-step explanation:

If x is the third number, then x−1 and x−2 are the second and first numbers.

10(x−2) + 10(x−1) = 10 + 10x

x − 2 + x − 1 = 1 + x

2x − 3 = 1 + x

x = 4

Answer:

1.6x10^-18 gram

Step-by-step explanation:

(5.3 x 10⁻²³ gram/molecule) x (20,000 molecule)

= (5.3 x 10⁻²³ x 2 x 10⁴) gram

= (10.6 x 10⁻²³⁺⁴) gram

= (1.06 x 10⁻²³⁺⁵) gram

= 1.06 x 10⁻¹⁸ gram

We need to find the mass of 20,000 molecules of oxygen. It can be calculated using unitary method. Here, we can multiply 20,000 molecules  by the mass of one oxygen molecule.

A supervisor must split 60 hours of overtime between five people. One employee must be assigned twice the number of hours as eac
insens350 [35]

Answer:

A. 10 hours for 4 employees and 20 hours for 1 employee.

Step-by-step explanation:

Okay, let's get to it! :D

So first, we need to set up an equation.

We know there are 60 total hours split between 5 people, and we can assign the number of hours 4 of the employees get as x. We also know that one employee gets double the amount of hours, so they would get 2x. Now, let's put that into an equation :)

60 = 2x + 4x

Now we add the x's together so the equation looks like this:

60 = 6x

To find x, we have to get it alone, so now we divide 60 by 6.

X = 10

But we're not done yet. X is the amount the 4 employees have to work, but because one employee has double the hours, we double our x-value to get 20 hours for that one employee.
