Answer:

19/6 cups

Explanation:

First, we need to transform the mixed number into a fraction as:

3\frac{1}{2}=\frac{3\cdot2+1}{2}=\frac{7}{2}

Now, we need to subtract 1/3 from 7/2, so:

\frac{7}{2}-\frac{1}{3}=\frac{7\cdot3-2\cdot1}{2\cdot3}=\frac{21-2}{6}=\frac{19}{6}

Therefore, she needs 19/6 cups more

When solving the equation, which is the best first step to begin to simplify the equation?
boyakko [2]

Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)

dem82 [27]

Answer:

The probability that a resident reports high satisfaction while the resident is a renter is Option(a) 13.7\%

Step-by-step explanation:

Given:

                               Levels of satisfaction

                      High      Medium     Low       Total

Owners          26             34               18           78

Renters           15            12                5            22

Total               41             46               23          110

The Resident is a renter.

Step 1:

To find the probability that a resident reports high satisfaction.

P(Renter- higher satisfaction)= Higher Satisfaction by render ÷ Total level of satisfaction

=\frac{15}{110}

=0.137

13.7\% is the probability that a resident reports high satisfaction.

Therefore, Option (a) is a correct answer.
