-10

6(5-3x)=7(10-2x). Plug -10 into each x and use PEMDAS which is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Plugging -10 in would look like: 6(5-3(-10))=7(10-2(-10)).

What you want to do is solve one side so lets solve the right side first: 2· -10 = -20. 10-(-20)= 10+20= 30. 7 · 30=210. Now that we have this side figured out it will be easier to figure the rest out.

3 · -10= -30. 5 - (-30)= 5+30=35. 6·35=210. Both sides come to out to be the same thing using -10.

6(5 - 3x) = 7(10 - 2x)

30 - 18x = 70 - 14x

-18x = 40 - 14x

-4x = 40

x = -10

Find the volume (in terms of pi) of a sphere of its surface area is 400 pi ft2

elixir [45]

$\bf \textit{surface area of a sphere}\\\\ SA=4\pi r^2\qquad \qquad \implies \stackrel{SA}{400\pi }=4\pi r^2\implies \cfrac{400\pi }{4\pi }=r^2 \\\\\\ 100=r^2\implies \sqrt{100}=r\implies \boxed{10=r} \\\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \qquad V=\cfrac{4\pi \boxed{10^3}}{3}\implies V=\cfrac{4000\pi }{3}$

A bacterial growth starts with 234 bacteria and doubles in population every 30 minutes.

Elina [12.6K]

Answer:

The rate of exponential growth of a bacterial culture is expressed as generation time, also the doubling time of the bacterial population. Generation time (G) is defined as the time (t) per generation (n = number of generations). Hence, G=t/n is the equation from which calculations of generation time (below) derive

Answer:

Area of square = Side²

Step-by-step explanation:

The area of a 2-D region, form, or flattened lamina in the planes is the quantity that represents its extent. On the 2-D surface or 3-D object, surface is its counterpart. A shape's area can be calculated by comparing it to squares of a specific size.
