Vedmedyk [2.9K]

Answer:

 2) 1/3

Step-by-step explanation:

The repeating decimal can be converted to a fraction by multiplying it by 10^n and subtracting the original value. n = number of repeating digits. This process cancels all of the repeating digits, so you can find the equivalent fraction.

  x=0.\overline{3}\\\\10x -x=3.\overline{3}-0.\overline{3}=3\\\\x=\dfrac{3}{9}\\\\0.\overline{3}=\dfrac{1}{3}

Albert wants to buy two pomegranates and some peaches
m_a_m_a [10]

1.19p+3.18≤10.00 can be used to determine the pounds of peaches Albert can buy.

Step-by-step explanation:

Given,

Cost of one pomegranate = $1.59

Cost of two pomegranate = 1.59*2 = $3.18

Cost of peaches per pound = $1.19

Cost of p pounds of peaches = 1.19p

Total amount of spent = $10.00

Cost of p pounds of peaches + Cost of two pomegranates ≤ Total to spend

1.19p+3.18\leq 10.00

1.19p+3.18≤10.00 can be used to determine the pounds of peaches Albert can buy.

Twice the sum of three and a number is 30. Find the number
DedPeter [7]

9514 1404 393

Answer:

  • 2(x +3) = 30
  • 12

Step-by-step explanation:

When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:

  2(x +3) = 30 . . . . an equation for the given conditions

__

We can solve this equation by dividing by 2:

  x + 3 = 15

  x = 12 . . . . . . subtract 3

The number is 12.
