Answer:

14 pages remain blank

Step-by-step explanation:

subtract 50-8 and u get 42. 42 is how many pages r left so u figure out 2/3 of 42 which is 28 so 28 pages are about her friends. To figure out how many pages are left blank u would subtract 42-28. 42-28=14 so 14 pages r left blank.

morpeh [17]

The standard numbers are obtained from the given numbers as follows;

  • 10⁷ → 10000000
  • 10⁵ → 100000
  • 10⁸ → 100000000
  • 10¹² → 1000000000000
  • 10⁶ → 1000000

<h3>Which method can be used to express the numbers in standard form?</h3>

The standard form of numbers is obtained by expressing the number completely and not using powers of 10

The given numbers in powers of 10 can be expressed in standard form by writing the specified number of zeros next to 1 given by the power of 10 as follows;

Number → Standard form

  • 10⁷ = 10000000
  • 10⁵ = 100000
  • 10⁸ = 100000000
  • 10¹² = 1000000000000
  • 10⁶ = 1000000

The value of y varies directly with x. If x = 3, then y = 21. What is the value of x when y = 105?
Vikentia [17]

Answer: 15

<u>Step-by-step explanation:</u>

varies directly means: \frac{y}{x} = k

Plug in the given values of x and y to solve for k: \frac{21}{3} = k  → 7 = k

Next, plug in the k-value of 7 and the given y value of 105 to solve for x:

\frac{105}{x} = 7

\frac{105}{x}(\frac{x}{7}) = 7(\frac{x}{7})

\frac{105}{7} = x

15 = x
