Answer: There are 175 pages in the book.

Step-by-step explanation:

If Elena read 20 more pages than Andre and she read 55 pages, to find out how much Andre read you have to:

55-20= the pages Andre read

55-20=35

Andre read 35 pages.

If Andre read 1/5 of the book, then to find how many pages are in the book, you have to multiply 35 x 5. (Multiply by the reciprocal)

35 x 5= 175

There are 175 pages in the book.

vfiekz [6]

Answer:

P(S&G) =0.7941

Step-by-step explanation:

From the question we are told that:

Sample size n=16+18=>34

N0 of  Large L=16

N0 of Small S=18

N0 large Green L_g=9

N0 of small White S_w=3

Therefore

Number of green marbles N0(G)=9+(18-3)

Number of green marbles N0(G)=24

Generally the Number of both small and green Marble is

N0 of (S&G)= 18 - 3 = 15

Generally the  probability that it is small or green P(S&G) is mathematically given by

P(S&G) = \frac{(18 + 24 - 15)}{(18 + 16)}

P(S&G) =0.7941

10p - (3p - 4) = 4(p + 1) + 9
andrezito [222]

Answer:

p = 3

Step-by-step explanation:

distribute parenthesis on both sides of the equation

10p - 3p + 4 = 4p + 4 + 9 ( simplify both sides )

7p + 4 = 4p + 13 ( subtract 4p from both sides )

3p + 4 = 13 ( subtract 4 from both sides )

3p = 9 ( divide both sides by 3 )

p = 3
