Why is it helpful to write a number as a product of primes

Debora [2.8K]4 years ago

Because if you are multiplying or dividing, you can regroup numbers to make it easy so exg
80 times 45 might look scary but it is really 2 times 2 times 2 times 2 times 3 times 3 times 5 times 5
regroup to make
(2 times 5) times (2 times 5) times (2 times 2 times 3 times 3)=10 times 10 times (6 times 6)=10 times 10 times 36=3600

dividing
188/132
188=2 times 2 times 47
44=2 times 2 times 3 times 11
so it becomes (2 times 2)/(2 times 2) times (47/(3 times 11))=1 times 47/33=47/33

Jay and Ted observed two points, P and Q, on a number line.
kobusy [5.1K]
Start at 0 and move to point P. To do this, we simply move left 1/8 of a unit. Similarly, we move 1/8 of a unit to go from 0 to point Q

So the distance from P to 0 is the same as the distance from Q to 0.

Therefore, the absolute values are the same

Answer: Choice A) Jay is correct because each point is 1/8 a unit away from 0

3(2x-5)= 21<br> solve it 2 different ways <br> plzz hurry i need help
docker41 [41]

Answer:

x = 6

Step-by-step explanation:

3 (2x - 5) = 21

=> 6x - 15 = 21

=> 6x = 21 + 15

=> 6x = 36

=> x = 36 / 6

=> x = 6

OR

3 (2x - 5) = 21

=> 2x - 5 = 21 / 3

=> 2x - 5 = 7

=> 2x = 7 + 5

=> 2x = 12

=> x = 12 / 2

=> x = 6

Hope it helps :)

Veronica bought 2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound. She also bought 4.8 pounds of ham.
Brrunno [24]

Answer:

Choose the correct answer from your choices.

Step-by-step explanation:

First, we find the price of the turkey by multiplying the weight of turkey by the price per pound.

2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound.

2.1 lb * 2.87 $/lb = $6.03

Then, we find the price of the ham by multiplying the weight of ham by the price per pound.

She also bought 4.8 pounds of ham. The price of the ham was 2.11 per pound.

4.8 lb * 2.11 $/lb = $10.13

Now we add the two prices together.

$6.03 + $10.13 = $16.16

The total price was $16.16
