Hello from MrBillDoesMath!

Answer:

12/55

Discussion:

Start by simplifying the numerator:

( 3/(5b) - 2/(5b)) / ( 1/(4b) + 2/(3b) ) = => as 3/(5b)- 2/(5b) = 1/(5b)

(1/(5b) / (1/(4b) + 2/(3b) ) = => multiply num., denom. by "b"

(b * 1/(5b)) / ( b/(4b) +2b/(3b)) = => as b/b = 1

(1/5) / (1/4 + 2/3) = => 1/4 = 3/12; 2/3 = 8/12

(1/5)/ ( 3/12 + 8/12) =

(1/5)/ ( 11/12) = => 1/ (11/12) = 12/11

(1/5) 12/11 =

12/55

Thank you,

Write the equation on the line passing through the two points (-2,11) and (5,-3)

nalin [4]

Answer:

y = - 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 11) and (x₂, y₂ ) = (5, - 3)

m = $\frac{-3-11}{5+2}$ = $\frac{-14}{7}$ = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 11), then

11 = 4 + c ⇒ c = 11 - 4 = 7

y = - 2x + 7 ← equation of line

Common denominators!

If you have to add... 3 fractions with 4 as the denominators: 
Then you can combine the numerators: 

a/c+ b/c = (a+b)/c and a/d + b/d + c/d = (a+b+c)/d 

Let's plug in the numbers.

a=3, b=1, c=1, d =4 
3/4 + 1/4 + 1/4 = 5/4 or 1 1/4! 

So the equation for the problem: 

Lt = L1+ L2 + L3 + L4 or 
L4 = Lt - L1 - L2 - L3 Plug in the numbers 

L4 ( remains ) = L total, 72 - L1 ( first cut at 30 3/4 ) - L2 ( second cut 12 1/4 ) - L3 ( 16 1/4 ) 

So 72 - 30 - 12 - 16 - 3/4 - 1/4 - 1/4 =? 
( break this down into simple terms and do it in your head... 

72 - 30 = 42, 42 - 21 = 30, 30 - 16 = 14, 14 - 3/4 = 13 1/4 - 1//4 = 13 - 1/4 = 12 3/4!

A pipe that's 36 inches long needs to be cut into 2 1/4-inch long pieces. How many pieces can be cut from this length of pipe? H

Mazyrski [523]

Answer:

16 inches

Step-by-step explanation:

2 1/4 = 9/4 inches

Number of pieces = 36 / 9/4

= 36 + 4/9

= 16 inches

For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
option 4
