Answer:

(5 x 6)x(3 x 2) is equal to 180

To find the answer, you have to solve them to see if they are equal to 180.

A) (5 + 6) + (3 + 2)    NO

simply cannot work because it's an addition of small numbers. This expression equals 16. Not equivalent.

B) (5 + 6) (3 + 2) (5 x 6) + (3 x 2)  NO

B doesn't make sense as it includes both the expressions together, including the initial expression which we are trying to find an equivalent answer, hence, it is going to equal more than the answer:  x > 180.  Solving for x is unnecessary as we know it is more.  

<u>No C? </u>

D) (3 x 2)x(5 x 6)  YES

This one works as the same numbers as the initial expression are equivalent and the expression uses the same math signs. This displays the commutative property of multiplication

Conclusion:

the Answer is D)

Two hiking groups made the purchases shown below. What is the cost of each item. GROUP 1: 6 muffins, 12 granola bars, Total=$26.
stepladder [879]

Answer:

Price of each muffin = $1.25

Price of each granola bar = $1.6

Step-by-step explanation:

Group 1:

6 muffins, 12 granola bars

Total money paid = $26.70

Group 2:

8 muffins, 15 granola bars,

Total money paid = $34.00

To find:

Price of each item?

Solution:

Let the price of one muffin = $x

Let the price of one granola bar = $y

As per group 1, the equation can be written as:

6x+12y=26.70\\\Rightarrow x+2y=4.45 .... (1)

As per group 2, the equation can be written as:

8x+15y = 34 .... (2)

Let us use elimination method to solve for x and y.

Multiplying equation (1) with 8 and subtracting (2) from it:

16y-15y = 35.6 - 34\\\Rightarrow y = 1.6

Using equation (1):

x+3.2=4.45\\\Rightarrow x = 1.25

Therefore, the answer is:

Price of each muffin = $1.6

Price of each granola bar = $1.25
