Rachel: 3 bracelets in an hour.
Oliver: 2 bracelets in an hour but has completed 5 bracelets

Rachel : y = 3x
Oliver : y = 2x + 5

Let x be the number of hours. y is the total number of bracelets made in x hours.

3x = 2x + 5
3x - 2x = 5
x = 5

It would take 5 hours for Rachel to have the same number of bracelet as Oliver.

Rachel: 3x = 3(5) = 15
Oliver: 2x + 5 = 2(5) + 5 = 10 + 5 = 15

Answer:

Hence, she will have the same number of bracelets as oliver after 5 hours.

Step-by-step explanation:

Rachel can make 3 bracelets in an hour. Oliver can make only 2 bracelets in an hour, but he already has completed 5 bracelets.

Let b be the total number of bracelets made.

so the number of bracelets made by Rachel in 'h' hours is: b=3h

and the number of bracelets made by Oliver in 'h' hours is: b=2h+5.

We are asked to find the value of 'h' so that the number of bracelets made by both of them are equal.

i.e.

3h=2h+5

⇒  3h-2h=5

⇒  h=5.

Hence, she will have the same number of bracelets as oliver after 5 hours.

( and they will make b=3×5=15 bracelets )

Please solve this 6-3 log2n=0
lutik1710 [3]
If that is 6-3(log2n)=0 then how you would go about solving it is by looking at log2n like x. In this case, for 6-3x=0,  x would have to  =2. So log2n has to =2. If log2n=2 and we assume that the base is 10 (because if there is no written base on a log then it is 10) then we need to rewrite the log to exponential form. Rewritten it's 10^2=2n. 100=2n, divide both sides by 2 and you get n=50.
