A book with a yellow sticker costs 50cents more than double a book wit3a red sticker

Mathematics
1 answer:
navik [9.2K]3 years ago
8 0

Answer:

50b>100b

Step-by-step explanation:

the book (b) is your variable in this case (a variable is just an item and im using b because it stands for books lol)

the book costs 50 cents, so we are going to put 50 cents in front of b(the books) so like this---->  50b: this reads as "the books are 50 cents."

now, the "more than" always means this sign ">"

and here's the tricky part, since it says " double a book with a red sticker." you're going to want to multiply ( 50*2=100), and we do this because of the word "double" (double means two) this is how you would write this scenario.

now im not sure if you wanted me to solve for it, but if curious you would just have to divide. the 50 and the 100 to get an answer.

B(x)=x+4, what is b(-10)
vovikov84 [41]

Answer:

B(-10)=-6

Step-by-step explanation:

we have

B(x)=x+4

we know that

B(-10) is the value of the function B(x) for the value of x=-10

so

substitute the value of x=-10 in the function

B(-10)=-10+4=-6

therefore

B(-10)=-6

Simplify the expression. Assume all variables are positive. <br> (r/32s)^8/5
balandron [24]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given expression is :

(\frac{r}{32s} )^{\frac{8}{5} }

It could be written as

(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{32} )^{\frac{8}{5} }

32 could be written as 2^{5}

So, replacing that in our expression

(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2^{5} } )^{\frac{8}{5} }

(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2} )^{5*\frac{8}{5} }

(\frac{r}{s} )^{\frac{8}{5} }*(\frac{1}{2} )^{8}

\frac{1}{256}*(\frac{r}{s} )^{\frac{8}{5} }

This is the simplified form of given expression.  :  Answer

Hope it will help :)
