Answer:

6 bags

Step-by-step explanation:

The GCF of 30 and 42 is 6.

30/6 = 5

42/6 = 7

To use all candy, put 5 fireballs and 7 jolly ranchers in each bag. You will make 6 bags.

Answer: Charges for  a hardcover book is  $6 and Charges for  a paperback book is  $4

Step-by-step explanation:

1) This problems belongs to linear equation in two variables. From this problem , we can say that we required  a pair of linear equation to solve linear equation in two variables.

2) lets create equation

let the charges for  a hardcover book is represented by variable x

let the charges for  a paperback book is represented by variable y

Creating equation related to Adams work

Adam sold 4 hardcover books and 10 paperback books .

So  Adams earning = (4 × x ) + ( 10 × y)

⇒ 4x + 10y = 64         ------equation 1                 [ given earning of Adam = 64 ]

Creating equation related to Barb work

Barb sold 5 hardcover books and 7 paperbacks for the same prices each

so Barb's earning = (5 × x ) + ( 7 × y)

⇒ 5x + 7y = 58         -------equation 2               [ given earning of Barb = 58 ]

so two equations are

4x + 10y = 64         ------equation 1       And

5x + 7y = 58         ------equation2

where variable x represents charges for  a hardcover book and variable y represents charges for paperback books


3)  lets solve two equation derived in step 2

4x + 10y = 64         ------equation 1       And

5x + 7y = 58         ------equation2

On multiplying equation 1 by 5 and equation 2 by 4 to make coefficient of variable x same.

5 × ( 4x + 10y = 64 )

= 20 x + 50 y = 320     ---------------equation 3

4 × ( 5x + 7y = 58 )

= 20x + 28y = 232       ----------------equation 4

subtracting  equation 3 from equation 4 we get

20x - 20x +50y - 28y = 320 - 232

⇒ 22y = 88

⇒ y = 88/22 = 4

On substituting value of y in equation 1 , we get

4x + 10× 4 = 64

⇒ 4x = 64 - 40 = 24

⇒ x = 24/4 = 6

Hence charges for  a hardcover book = x = $6

And charges for  a paperback book = y = $4

denpristay [2]

Answer:

calculus, geometry, arithmetic among a few

Step-by-step explanation:

Mathematics is involved in winter Olympics in different aspects like arithmetic which helps in scores, measurements, quantities and motion  of the sport  like hockey, running.

Scoring in ice skating involves arithmetic operation when an individual element is assigned points and  judged on performance level( triple axle is 3 points but overall performance and artistry is measured by the judges).  

Another is Calculus  which helps to understand the change in acceleration and velocities while each skaters start at zero then win, Lines in Geometry such as the finish/start/sight lines helps players with angles of reflection, measuring angles and angles of incidence.
