how to find out L C M of common division method ​

Answers

Step-by-step explanation:

To find the LCM by division method, we write the given numbers in a row separately by commas, then divide the numbers by a common prime number. We stop dividing after reaching the prime numbers. The product of common and uncommon prime factor is the LCM of given numbers.

For example

2 24,12

2 12,6

2 6,3

3 2,1

2 1,1

LCM=2×2×2×3×2

Determine the solutions of the equation |x – 3| = 11. 1. Rewrite for two solutions: (x – 3) = 11, –(x – 3) = 11 Solve for x in each equation. What are the solutions to the equation? x = –14, –8 x = –14, 8 x = –8, 14 x = 8, 14

Answers

Answer: C. x=-8,14

Step-by-step explanation:

C

Answer:

              x = 14,  –8

Step-by-step explanation:

                 |x – 3| = 11

(x - 3) = 11                         - (x - 3) = 11

x - 3 = 11                           - x + 3 = 11

 x = 11 + 3                          -x  = 11 - 3

 x = 14                                  -x = 8

                                             x = -8

If m∠PTQ = 3y –10 and m∠QTR = y, find the value of y so that ∠PTR is a right angle

Answers

Answer:

y = 25

Step-by-step explanation:

Given that,

m∠PTQ = 3y –10 and m∠QTR = y

We need to find the value of y so that ∠PTR is a right angle.

For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,

3y –10 + y + 90 = 180

Taking like terms together

3y+y = 180 -90 +10

4y = 100

y = 25

So, the value of y is 25.

If DE bisects <ABC.find the value of x if m<ABC=7x+29 and m<DBC=99°​

Answers

Answer:

19

Step-by-step explanation:

If DE bisects  <ABC, this means that <ABE = <EBC

Also <DBC+<EBC = 180

99+<EBC = 180

<EBC = 180-99

<EBC = 81

Also <ABC =<ABE+<EBC

<ABC =<EBC+<EBC

7x+29 = 81+81

7x = 162-29

7x = 133

x = 133/7

x = 19°

Hence the value of x is 19°

15. PART A: Write an algebraic expression for each verbal expression "the product of 9 and t squared, increased by the sum of the square of t and 2" *

Answers

Answer:

9t²+(t²+2)

Step-by-step explanation:

The product of 9 and t squared is expressed as 9×t² (product means multiplication)

9×t² = 9t²

Also, sum of the square of t and 2" is expressed as t² + 2 (sum means addition)

Finally, if the product of 9 and t squared, increased by the sum of the square of t and 2", the final expression will be the sum of the two expressions gotten. {Increment also means addition} i.e 9t²+(t²+2)

The algebraic expression is 9t²+(t²+2)

+) Six times the sum of a number and -1 is the same as 2 more than 8 times the number. Find the number.


Answers

Answer:

-4

Step-by-step explanation:

6(a+(-1)) = 8a + 2

then:

6(a-1) = 8a + 2

6*a + 6*-1 = 8a + 2

6a - 6 = 8a + 2

6a - 8a = 2 + 6

-2a = 8

a = 8/-2

a = -4

Check:

6(-4-1) = 8*-4  +  2

6*-5 = -32 + 2 = -30
