Answer: -3/4

Step-by-step explanation:

first you have to apply distributive, which would end in 16x +24 =12, then apply the substraction property, which would end in 16x= -12 then pass 16 as dividing which would end in -12/16, which simplified is -3/4. Hope this helps!

Which pair is equivalent? 5/4 & 1 2/4 . 4 6/7 & 7/34. 3 3/5 & 18/5. 12/9 & 2 3/9

Drupady [299]

3 3/5 & 18/5 are both equivalent

Step-by-step explanation:

3 3/5 = 18/5

<u>Write the mixed number as an improper fraction</u>

Step 1: Multiply the denominator by the whole number

5 × 3 = 15

Step 2: Add the answer from Step 1 to the numerator

15 + 3 = 18

Step 3: Write answer from Step 2 over the denominator

18/5

Therefore, 3 3/5 is equivalent to 18/5

Simplify the expression by factoring, showing the steps in your work.

alexdok [17]

Given:

$$\frac{12 x^{2}+31 x+7}{16 x^{2}+8 x+1}$

To find:

The simplified expression by factoring.

Solution:

Let us factor the numerator:

$12 x^{2}+31 x+7$

31x can be written as 3x + 28x.

$=\left(12 x^{2}+3 x\right)+(28 x+7)$

Take 3x common in 1st two terms and 7 common in next two terms.

$=3 x(4 x+1)+7(4 x+1)$

Make sure the remaining terms in the both brackets must be same.

Now, take out common factor (4x + 1).

$=(4 x+1)(3 x+7)$

In the same way, factorize the denominator:

$16 x^{2}+8 x+1$

8x can be written as 4x + 4x.

$=(16 x^{2}+4 x)+(4x+1)$

Take 4x common in 1st two terms and 1 common in next two terms.

$=4x(4 x+1)+1(4x+1)$

Make sure the remaining terms in the both brackets must be same.

Now, take out common factor (4x + 1).

$=(4x+1)(4x+1)$

Substitute the terms we found for numerator and denominator:

$$\frac{12 x^{2}+31 x+7}{16 x^{2}+8 x+1}=\frac{(4 x+1)(3 x+7)}{(4 x+1)(4 x+1)}$

Cancel the common factors.

$$=\frac{3 x+7}{4 x+1}$

The simplified expression is $\frac{3 x+7}{4 x+1}$ .

Write an equation of the perpendicular bisector of the segment with endpoints

Kruka [31]

Answer:

Step-by-step explanation:

Midpoint of line segment = (1,-3)

Slope of line segment = (-1-(-5))/(3-(-1)) = -3/2

Perpendicular bisector:

y+3 = ⅔(x-1)

y = ⅔x - 11/9
