If the mean of the four numbers 2x and 12 is 10, then x is

Lelu [443]

Answer:

Step-by-step explanation:

The mean of 2x and 12 is (2x+12)/2, so we get the equation:

(2x+12)/2 = 10 =>

x+6=10

x = 10-6 = 4

* Your question states four numbers, but you write only two... the answer could be wrong because of that.

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.
