Solve Problems Using Division David and Jake a are making cookies. They each get 2 rolls of cookie dough and they are cutting up
trapecia [35]

Answer:

<u>David will have the most cookies and he will have two cookies more than Jake</u>

Step-by-step explanation:

1. Let's calculate how many cookies will David cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/8)

Number of cookies = 16

2. Let's calculate how many cookies will Jake cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/7)

Number of cookies = 14

<u>David will have the most cookies and he will have two cookies more than Jake</u>

2(3/5x+3). How would I get that answer
Airida [17]

Answer: \frac{6}{5}x + 6

Step-by-step explanation:

       We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.

       Given:

2(3/5x+3)

       Distribute:

2 * (3/5x) + (2 * 3)

6/5x + 6

       Answer:

\frac{6}{5}x + 6
