I'm not sure, but I think you just need to do 9x2 (18)
Then add 27 to it. (45)
Therefore, the answer would be 45.

Muskaan had 157 dollars to spend on 6 books. After buying the she had 13 dollars. How much did each book cost?

nirvana33 [79]

Answer:

the cost of each book = $24

Step-by-step explanation:

(if all the books have the same price)

Let x be the price of one book

“She had $157 and After buying 6 books ,she was left with 13$“ means

“157 = 6x + 13”

now we have an equation to solve :

157 = 6x + 13

⇔ 157 - 13 = 6x

⇔ 144 = 6x

⇔ 24 = x

Answer:

$41.1units^2$

Step-by-step explanation:

$A=\frac{h_{b}b }{2} \\=\frac{8*4}{2} \\=16units^2$ (triangle)

$A=\frac{\pi r^2}{2}\\\frac{\pi 4^2}{2}\\=25.13units^2$ (semicircle)

Add both together

$16+25.13\\=41.13units^2$

convert the following logarithmic equation to the equivalent exponential equation. Use the caret (^) to enter exponents. y=ln x

GarryVolchara [31]

1. To solve this problem, you need to remember that an exponential function has the following form:

f(x)=a^x

"a" is the base and "x" is the exponent.

2. It is important to know that the logarithmic functions and the exponential functionsare inverse. Then, you have:

y=ln x
 e^y=e^(lnx)
 e^y=x

3. Therefore, the answer is:

x=e^y
