Answer:

x=13

Step-by-step explanation:

x+2x=3x

-6+9+-19=-16

3x-16=23

+16     +16

3x=39

divide by 3 on both sides.

x=13

To find x:

ON is parallel to LM

8x - 8 = 7x + 4

-7x        -7x

1x - 8 = 4

     +8   +8

1x = 12

---    ---

1        1

x = 12

8(12) - 8 = 7(12) + 4

96 - 8 = 84 + 4

88 = 88

------------------------------------

To find y:

NM is parallel to OL

x - 5 = 3y - 6

12 - 5 = 3y - 6

7 = 3y - 6

+6      +6

13 = 3y

---    ---

3      3

13/3 = y

Check:

12 - 5 = 3(13/3) - 6

7 = 13 - 6

7 = 7

Question:
mash [69]

The least common denominator is the Least Common Multiple (LCM) of the divisors 3 and 4. Since these numbers have no common factors, their LCM is

... 3·4 = 12

The least common denominator of your fractions is 12.

... 1/3 = (1/3)·(4/4) = 4/12

... 3/4 = (3/4)·(3/3) = 9/12

S=hp+2b solve for h i forgot the word to decribe how i forgot to do tis
irga5000 [103]

To solve for h, you need to isolate/get h by itself in the equation:

s = hp + 2b     Subtract 2b on both sides

s - 2b = hp + 2b - 2b

s - 2b = hp           Divide p on both sides to get h by itself

\frac{s-2b}{p} =\frac{hp}{p}

\frac{s-2b}{p} =h
