Answer:

a = 6

Step-by-step explanation:

Rearrange: 7 × a - 3 - (3 + 6 × a) = 0
Simplify, so it now looks like this: a - 6 = 0
Add 6 to each side, so it now looks like this: a = 6

I hope this helps!

Answer:

$\frac{1}{4}$ of the books in the book store are mystery fiction books.

Step-by-step explanation:

Let x represent all the books in the books store.

Then, the fraction of books that are fiction books is $\frac{3}{4}x$

We have that; $\frac{1}{3}$ of the fiction books are mystery books.

The fraction of the books at the bookstore that are mystery fiction books is $\frac{1}{3}\times \frac{3}{4}x=\frac{1}{4}x$ .

Therefore $\frac{1}{4}$ of the books in the bookstore are mystery fiction books.

Answer:

y'= 5x^4 + 5^x In(5)

Step-by-step explanation:

Differentiate with Respect to x

f(x)'=5x^4 + In(5^x)

f(x)'= 5x^4 + x In(5)

with respect to x, we have

y'= 5x^4 + y In(5)

y'= 5x^4 + 5^x In(5)

What is the solution of 6x= 15

balandron [24]

Answer:

2.5

Step-by-step explanation:

When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.

Because we don't know what x is, we have to work backwards.

The opposite of multiplying is dividing, so here we can do...

15/6 and that equals 2.5

To check you replace x with 2.5 like so,

6(2.5)= 15 and it is true!

Hope this helps and have a great day!

Find the ratio of book price to number of pages for each ordered pair. Round your answer to the nearest hundredth. A 3-column ta

Harlamova29_29 [7]

The ratio of book price to number of pages for the ordered pairs a, b , and c are:

A = 0.05
B = 0.05
C = 0.043

The ratio of book price to number of pages can be evaluated for each ordered pairs as follows;

For a = 20.00/400 = 0.05

For b = 6.25/125 = 0.05

For c = 15.0/350 = 0.043

Therefore, ratio of book price to number of pages for the ordered pairs a, b , and c are:

a = 0.05

b = 0.05

c = 0.043
