Solve for x. x/5=20 what does X equalllll

When you have a variable in an equation, you have to isolate it on one side. To do this, look for any other numbers and if they are added, multiplied, divided, or subtracted from x.

Next, you take that number and do the opposite of its operation to the other side.

In this example, you have x/5=20

So we first identify that x is being divided by 5

Then we take 5, and do the opposite of division to 20.

So x/5=20 turns into x = 5x20

Then we simplify, x = 100.

If your not sure your answer is write, you can always put the value of x back into the first equation and solve to see if its true:

X/5=20

100/5=20

20=20

Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Oliver spent 4 an

LUCKY_DIMON [66]

The time taken by Oliver to complete the work is less than or equal to twice the work done by Karissa.

Option B shows the correct equation of inequality to write the time taken to complete the work.

<h3>What is inequality?</h3>

Inequality can be defined as a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Given that Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Also, the time taken to complete the project is,

Oliver = 4 and one-fourth hours

Karissa = K hours

As per the given condition, the work done by Oliver should not be more than twice the work done by Karissa. It can be equal or less. So we can write this in equation form as,

Oliver $\leq$ 2 Karissa

$4\dfrac {1}{4} \leq 2K$

Hence Option B shows the correct equation of inequality to write the time taken to complete the work.

Please help. question in the photo!

well, if m = 1, let's see, then f(x) = √(mx) = √(1x) = √x

and then g(x) = m√x = 1√x = √x

well, if both equations are equal, then their ranges are also equal.

now, if m = "any positive real number"

f(x) = √(mx) = √m √x will yield some value over the y-axis

g(x) = m√x will yield some range over the y-axis, however, "m" is a larger value than "√m".

what that means is that so long "m" is a positive real number, the ranges of f(x) and g(x) will be the same over an infinite range on the y-axis, even though g(x) is moving faster than f(x), f(x) is moving slower because √m makes a stretch transformation which is smaller than one "m" does.
