Rewrite 5/ 16 + 6/ 20 with a common denominator.

2 answers:

5 0

25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.

Answer:

49/80

Step-by-step explanation:

For getting a common denominator, each term must be multiplied in numerator and denominator by the denominator of the other term.

For example:

The 5/16 term must be multiplied by 20 (both 5 and 16)

The 6/20 term must be multiplied by 16 (both 6 and 20)

The terms would be like this:

(5x20)/(16x20)+(6x16)/(20x16)

The result would be:

100/320+96/320

As common denominator is already obtained, the expression could be one.

(100+96)/320=196/320

Now, the previous expression could be simplified. If we divide the numerator and the denominator by 4, the following result is obtained:

(196/4)/(320/4)=49/80

The expression with common denominator would be: 49/80

HURRY In the figure, j∥k and m∠2 = 117°. What is the m∠3 ?

Andreyy89

Answer:

∠ 3 = 63°

Step-by-step explanation:

∠ 2 and ∠ 3 are adjacent angles and supplementary, thus

∠ 2 + ∠ 3 = 180°, that is

117° + ∠ 3 = 180° ( subtract 117° from both sides )

∠ 3 = 63°

Please Help!!! What is the end behavior of function h? h(x)=2(x-3)^2 As x approaches negative infinity, approaches negative infi

kramer

Answer:

Step-by-step explanation:

Function to be graphed is,

h(x) = 2(x - 3)²

Function 'h' is a quadratic function.

Since, the coefficient of the leading term (term with the highest power) is positive, parabola will open upwards.

Both the ends of the parabola will be upwards (towards positive infinity).

As x approaches to negative infinity, h(x) approaches to positive infinity.

As x approaches to positive infinity, h(x) approaches to positive infinity.

Answer:

$\frac{x - 4}{x - 3}$

Step-by-step explanation:

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

Lets split the numerator and denominator.

$= > \frac{ {x}^{2} - 4x - 4x + 16}{ {x}^{2} - 3x - 4x + 12}$

Lets factorise the numerator and denominator.

$= > \frac{x(x - 4) - 4(x - 4)}{x(x - 3) - 4(x - 3)}$

$= > \frac{(x - 4)(x - 4)}{(x - 3)(x - 4)}$

Cancelling x - 4 from numerator and denominator ,

$= > \frac{x - 4}{x - 3}$

If j // l, m<1 = 135, m<2 = 55, and m<3 = 45, list all other parallel lines. Justify your answers. Show work if any.

sergejj [24]

Answer:

Step-by-step explanation:

The supplement to ∠1 = 180°-135° = 45° = ∠3, so m is parallel to j and l.

∠2 ≠ 45° and ∠2 ≠ 135°, so k is not parallel to j, l, or m.

Greg started with a certain number of quarters. He then decided on a number of quarters he would save each day. He added the qua

lbvjy [14]

He started with 17 quarter's. He had a certain number of quarters he added to his collection each day, on day two he had 26, and two days later he had 35, meaning he increased the amount of quarters my 9 over two day's, so I subtracted 9 from 26 because if you do you can remove the quarters he added in from the ones he started with, so the answer is: He started with 17.
