Answer:

x = -59/66

Step-by-step explanation:

Solve for x over the real numbers:

log(7) - log(x + 1) = log(66)

Subtract log(7) from both sides:

-log(x + 1) = log(66) - log(7)

Multiply both sides by -1:

log(x + 1) = log(7) - log(66)

log(7) - log(66) = log(7) + log(1/66) = log(7) + log(1/66) = log(7/66) = log(7/66):

log(x + 1) = log(7/66)

Cancel logarithms by taking exp of both sides:

x + 1 = 7/66

Subtract 1 from both sides:

Answer:  x = -59/66

On the first day of vacation, you read one-quarter of a novel. On the second day, you read half of the remaining pages. On the t
OverLord2011 [107]

The computation shows that the number of pages is 320.

The number of pages read in this second day will be 120.

<h3>How to illustrate the information?</h3>

Fraction read on first day = 1/4

Fraction news on second day = 1/2 × 3/4 = 3/8

Fraction read on last day = 1 - (1/4 + 3/8) =3/8

The number of pages that the book has will be:

= 3/8 × x = 120

0.375x = 120

x = 120/0.375

x = 320

The number of pages is 320.

b. The number of pages read on this second day will be:

= 3/8 × 320

= 120

r-ruslan [8.4K]
94 if your using the whole frame the math is 5×7=35 we have 2 sides do times 35 by 2 35×2=70 then we do 1×7=7 for the outside of the game then do 7 times 2 b/c you have 2 sides the do your final side by doing 5×1=5 then times that by 2 and you get 10 .70+14+10=94

At noon of a certain day, when 5 pens and 3 pencils were placed in a drawer, the ratio of the number of pens to the number of pe
Molodets [167]

The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.

So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
