The factors of -12 are: +-(1, 2, 3, 4, 6, and 12).
The factors of 15x are: +(1, 3, 5, 15, and x).
Since the only factors that the two numbers share are 3 and 1, those are your common factors with 3 as your GCF.

a deli sells a sandwich spread for 6.40 per pound. how much do you have to pay for 24 ounces of the spread

rjkz [21]

In the given question the most important part is convert ounce to pound and then the problem becomes easy. We already know
1 ounce = 0.0625 pounds
Then
24 ounce = 0.0625 * 24 pounds
= 1.5 pounds
Now let us focus on the problem in hand and the information's that are already given in the question.
The cost per pound of the sandwich sold by Deli = 6.40
Then
The cost of 1.5 pound of sandwich sold by Deli = 6.40 * 1.5
= 9.60
So the cost of 24 ounces of spread is 9.60.

S is the centroid of triangle NQL. What is the length of NR?

svetoff [14.1K]

ANSWER

The length of NR is
$36 \: \: units$

EXPLANATION

The centroids divides the medians in the ratio
$2:1$
For instance

$|NS|:|SR|=2:1$

But

$|NS| = 9n - 12$

$|SR|=3n$

We substitute all these values in to the above relation to obtain,

$(9n - 12):3n=2:1$

This can be rewritten as

$\frac{9n - 12}{3n} = \frac{2}{1}$

We cross multiply to obtain,

$1(9n - 12) = 2 \times 3n$

This implies that,

$9n - 12 = 6n$

We group like terms to obtain,

$9n - 6n = 12$

This simplifies to give us,

$3n = 12$

$n = 4$

We can now determine each length as follows,

$|NS| = 9(4 ) - 12$

$|NS| = 36- 12$

$|NS| = 24$

$|SR|=3 \times 4$

$|SR|=12$

From the diagram,

$|NR|=|NS|+|SR|$

$|NR|=24 + 12$

$|NR|=36 \: units$
