tyra has 12 2/3 cups of sugar. if r is the amount of sugar needed for one batch of cookies, the expression 12 2/3 ÷ r can be use
olga nikolaevna [1]

ANSWER

She can make 19 batches of oatmeal.

EXPLANATION

First we can change the mixed number into an improper fraction:

12\frac{2}{3}=12+\frac{2}{3}=\frac{12\cdot3}{3}+\frac{2}{3}=\frac{36}{3}+\frac{2}{3}=\frac{38}{3}

In this problem, r = 2/3. The division is:

12\frac{2}{3}\div r=\frac{38}{3}\div\frac{2}{3}

Using the KFC rule:

\frac{38}{3}\div\frac{2}{3}=\frac{38}{3}\times\frac{3}{2}

Solving we can see that the denominator of the first fraction can be simpliied with the numerator of the second fraction:

\frac{38}{3}\times\frac{3}{2}=\frac{38}{1}\times\frac{1}{2}=\frac{38}{2}=19

Tyra can make 19 batches of oatmeal with 12 2/3 cups of sugar.

Which of the following is a solution of x2 + 2x + 8? (1 point)
Mrrafil [7]

<u>Answer</u>

−1 + i times the square root of 7


<u>Explanation</u>

x² + 2x + 8

I will use the complete square method to find the value of x.

x² + 2x + 8

x² + 2x = -8

x² + 2x + (2/2)² = -8 + (2/2)²

x² + 2x + 1 = -7

(x + 1)² = -7

x + 1 = √(-7)

x = √(-7) - 1

    = i√7 - 1

   = -1 + i√7

<em>−1 + i times the square root of 7 </em>
