There are 5 candy canes for every 9 presents. How many candy canes are there if there are 108 presents? (PLEASE SHOW YOUR WORK TOO! its for a grade:( )

Answers

Answer:

60 candy canes

Step-by-step explanation:

To find how many candy canes we have to remember that there are 5 candy canes for every 9 presents.

108 is divisible by 9 so we do the equation:

108 ÷ 9 = 12

Now we multiply 12 by 5 since theres 5 candy canes per 9 presents

12 × 5 = 60

To check our work we can divide-

9 ÷ 5 = 1.8

108 ÷ 60 = 1.8

Point C is the image of C (-4, -2) under a reflection across the y-axis.

What are the coordinates of C?

Answers

Answer: (4,-2)

Step-by-step explanation:

if you reflect a point across the y-axis, that point must be on the same horizontal line then to the pre-mage meaning the y coordinates must remain the same. From their we want the points on both sides of the t-axis to have the same distance. x and -x have the same distance from 0. Therefore this means you will need to take the opposite of X.

So point (x,y) being reflecting over the y-axis will give us (-x,y).

(x , y)--->(-x,y) mean you have (-4,-2)---->(4,-2)

What value of c is a solution to this equation?
–5=–3(c–2)–8

Answers

Answer:c=1

Step-by-step explanation:Step 1: Simplify both sides of the equation.

−5=−3(c−2)−8

−5=(−3)(c)+(−3)(−2)+−8(Distribute)

−5=−3c+6+−8

−5=(−3c)+(6+−8)(Combine Like Terms)

−5=−3c+−2

−5=−3c−2

Step 2: Flip the equation.

−3c−2=−5

Step 3: Add 2 to both sides.

−3c−2+2=−5+2

−3c=−3

Step 4: Divide both sides by -3.
