Every New Year's Day, Cody brings 15 candies for each of his grandchildren and
12 more candies for the adults to share.
Let g represent the number of Cody's grandchildren and c represent the total
number of candies he brings.
Find the value of c when g = 7.
C= ?

Answers

Answer:

c = 117

Step-by-step explanation:

g=7

c = 15g + 12

c = 15x7 + 12

c = 105 + 12

c = 117

C=117 is the correct answer

Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?

Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?

Answers

Step-by-step explanation:

If Aleah buys 2 DVDs for $6 and 2 CDs for $8 we can well assume that the DVDs are $3 dollars each and the CDs are 4 Dollars Each. If ling wants to buy 4 DVDs You would multiply how many DVDs she's buying with the price of the DVDs so (4x3=12) so Ling would have to pay $12 for the DVDs and $8 on the CDs

Pierre wants to spend $20 so with the previous information we can come to the solution that Pierre can buy 4 DVDs and 2 CDs for $20.

Answers

Answer:

If you multiply or divide both the top of a fraction and the bottom of a fraction by the same number, so for example:

[tex]\frac{2}{4}[/tex]÷[tex]\frac{2}{2} = \frac{1}{2}[/tex]

1/4 = 2/8

4/2 = 2/1 or 2

2/3 = 4/6

6/8 = 3/4

1/3 = 2/6

1/4 = 2/8

1/2 = 2/4

4/6 = 2/3

3/6 = 1/2

Answerk:

The answer is

[tex] \frac{1}{2} = \frac{2}{4} = \frac{3}{6} \\ \frac{2}{3} = \frac{4}{6} [/tex]

Think about this as a cake on a table.

You want to eat the top — so you slice across horizontally.

When you have just the bottom left on the table, you will have a rectangle shape

Another hint is that the question says a "right rectangular pyramid". So no matter how you slice a pyramid, the bottom of each slice will look the same as the name. In this case "rectangular"

PS: I've attached a sketch of what it looks like before & after slicing.
