147 =20x+47
147 is less than or equal to 20 multiplied by the number of hours she works (x) plus 47 the amount of money she already has
Domain has to do with x, the domain is - infinity to + infinity... for range, the highest value this function can take is 4, when x equals 5
Answer:. We assume, that the number 400 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 400 is 100%, so we can write it down as 400=100%.
4. We know, that x is 6.5% of the output value, so we can write it down as x=6.5%.
5. Now we have two simple equations:
1) 400=100%
2) x=6.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
400/x=100%/6.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 6.5% of 400
400/x=100/6.5
(400/x)*x=(100/6.5)*x -
400=15.3846153846*x -
400/15.3846153846=x
26=x
x=26
now we have:
6.5% of 400=26

It’s 450 du it’s just 18 Times 25
