To use the lowest common denominator (LCD), you need to factor each of the numbers. Then you need to see what's common.

3: 1 and 3

4: 2 and 2

Here there's nothing in common, so our common denominator has all the factors - 1, 3, 2, 2. 1 x 3 x 2 x 2 = 12.

3/4 would be 9/12 as we multiply both parts of the fraction by. We get from 4 to 12 by multiplying by 3.

1/3 would be 4/12 as we multiply both parts by 4.

Thus,

3/4 - 1/3 = 9/12 - 4/12 = 5/12

The LCD of 3 and 4 is 12. To make 4 into 12, we multiply it by three, so 3 would also have to be multiply by 3, turning 3/4 into 9/12.

The same thing applies to 1/3, only it needs to be multiplied by 4. So it would become 4/12

9/12 - 4/12 = 5/12

Select the correct answer. Which expression is equivalent to this polynomial? 15x − 24 A. 5(3x − 8) B. 3(5x − 5) C. 3(5x − 24) D
Scilla [17]

15x-24

the answer is not B because 3*-5= -15, we need -24

the answer is not C because 3*-24= -72

the answer is not A because 5*8= 40

Answer :

D. 3(5x − 8)

(3)(5x)(3)(-8)

15x-24= 15x-24

PLZ ANSWER ASAP!!!!! Part B
bazaltina [42]

The equation of the linear regression  is \^ y = 3.58125\^x + 202.575

<h3>Graphing tool</h3>

To determine the line of best fit, we make use of a graphing tool

See attachment for the graph of the line of best fit

<h3>The equation</h3>

From the graphing tool, we have the following calculation summary

  • Sum of X = 440
  • Sum of Y = 3601.5
  • Mean X = 44
  • Mean Y = 360.15
  • Sum of squares (SSX) = 1440
  • Sum of products (SP) = 5157

The regression Equation is then represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = \bar y - b \times \bar x

b = \frac{5157}{1440}

b = 3.58125

Also, we have:

a = \bar y - b \times \bar x

a= 360.15 - (3.58\times 44)

a = 202.575

So, the linear regression equation is:

\^ y = 3.58125\^x + 202.575

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What
trapecia [35]

Answer: The greatest number of cups of yogurt MOnica can buy is 14.

Step-by-step explanation:

If she  need to buy a gallon of milk then it means that $2.50  will be deducted from the money .  

Use the the inequality to solve for how many cups of yogurt Monica can buy

1.20x + 2.50 ≤ 20

             -2.50   2.50

1.20x ≤ 17.5

x≤14.5833...  

which means the greatest number of  cups of yogurt Monica can buy is 14.
