the equation us:
2n + 15 = -42

At a store, markers are sold in packages of 12 and pens are sold in packages of 8. What is the least amount of markers and pens
liubo4ka [24]

Given:

Markers are sold in packages of 12 and pens are sold in packages of 8.

To find:

Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens

Solution:

To find the least amount of markers and pens, we need to find the LCM of 12 and 8.

Prime factors of 8 and 12 are

8=2\times 2\times 2

12=2\times 2\times 3

To find the LCM, multiply all factors but the common factors are included only once.

LCM(8,12)=2\times 2\times 2\times 3

LCM(8,12)=24

Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.

Help me pleasssseeeeeee
fgiga [73]

Answer:

  d. Distributive property

Step-by-step explanation:

The <em>Distributive property</em> of multiplication over addition is what allows you to multiply each of the terms in parentheses by the factor outside parentheses. It tells you ...

  a(b +c) = ab + ac

It works both ways, also allowing you to remove a common factor to outside parentheses.
