Answer:

1 3/4 cups

Step-by-step explanation

Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.

5 1/2 - 3 3/4 = 1 3/4

Use the properties of operations to determine if each pair of expressions is equivalent
SIZIF [17.4K]

Using the properties of operations the given pair of expressions are not equivalent

<u>Solution:</u>

Given that, we have to use the properties of operations to determine if each pair of expressions is equivalent

<em><u>And the two expressions are:</u></em>

\frac{1}{2}(4-2 x) \text { and } 2-2 x

Now, we know that, there are four (4) basic properties of operations:

<em>Commutative, Associative, Distributive and Identity. These properties only apply to the operations of addition and multiplication.</em>

So, if we observe we can apply distributive property on 1st expression

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

\begin{array}{l}{\frac{1}{2}(4-2 x) \rightarrow \frac{1}{2}(4)-\frac{1}{2}(2 x)} \\\\ {\rightarrow 2-x}\end{array}

Here the resulting expression is 2 – x and it is not equivalent to 2 – 2x

Hence, the given two expressions are not equal.

Lady bird [3.3K]

Answer:

The Check that hasn't been cleared yet is for $372.15.

Step-by-step explanation:

168.48+ 168.93+ 177.78+ 177.93= 693.12

887.79- 693.12= 194.67

1,065.27- 887.79= 177.48

194.67+ 177.48= 372.15

To check your answer:

372.15+ 693.12= 1,065.27

Hope this helped you!! (:

trapecia [35]

Answer:

10.21 feet.

Step-by-step explanation:

circumference of circle with diameter d is given by \pi d

where r is the radius of the circle.

_____________________________

given

diameter = 6 1/2 = 13/2 feet

\thus, circumference of circle is calculated as following

circumference = \pi *13/2 = 22/7 * 13/2\\circumference = 11*13/7*2 = 143/14 = 10.21

Thus, circumference of given circle is 10.21 feet.
