Divide the sum of 3/8 and -5/12 by the reciprocal of 16/27 x(-15)/8

Mathematics

Travka [436]3 years ago

Answer:

First find the sum of 3/8 and -5/12

That is

3/8 - 5/12

First find the common denominator

The common denominator is 24

We get

3/8 - 5/12 = 3(3) - 5(2) / 24

= 9 - 10 / 24

= - 1 / 24

Next find the product of 16/27 x(-15)/8

That's

16/27 × -15/8

= -10/9

Next reverse -10/9

Which is -9/10

Next we divide it by = -1 /24

so we get

-1/24 ÷ -9/10

Change the sign to (×) and reverse the second fraction

We get

-1/24 × -10/9

= 5 / 108

Hope this helps

The perimeter of an airplane ticket is 32 centimeters. The area is 60 square centimeters. What are the dimensions of the ticket
victus00 [196]
We model the ticket as a rectangle.
 For this case what you should know is that the perimeter of the rectangle is given by:
 P = 2w + 2l
 The area of the rectangle is given by:
 A = w * l
 In both cases:
 w: width
 l: long
 We have the following system of equations:
 32 = 2w + 2l
 60 = w * l
 Solving the system we obtain:
 The dimensions of the ticket are:
 (10 cm) * (6 cm)
 Answer:
 the dimensions of the ticket are:
 (10 cm) * (6 cm)
 Note: see attached image for system solution

When I add or subtract fractions, first I must convert the
fiasKO [112]
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.

Help meeeee doooo thissss
lesya692 [45]

Answer:

B:  x=-5  and x=4

Step-by-step explanation:

f(x)= x^2 + x -20

To find the zeros we replace f(x) with 0

0= x^2 + x -20

now we solve for x

LEts factor x^2 + x -20

sum is +1  and product is -20

5 * (-4)= -20

5 + (-4) = +1

x^2 + 5x - 4x - 20 = 0

(x^2 + 5x)+(- 4x - 20) = 0

x(x+5) -4 (x+5) = 0

(x-4)(x+5)=0

Set each factor =0 and solve for x

x- 4 =0 so x=4

x+5 =0 so x=-5

x=-5  and x=4

Cloud [144]

Answer:

p = 35

Step-by-step explanation:

(2p + 5) + (3p) = 180 \\ 5p + 5 = 180 \\ 5p = 180 - 5 \\ 5p = 175 \\  \\ p =  \frac{175}{5}  \\  \\ p = 35

Add 1 1/3 + (−5/6) = ?
Aleks [24]
1 1/3 = 4/3 (because (3 * 1 + 1) / 3)

We need both parts of sum to have common denominator.
Second part have denominator = 6.
When we multiply nominator and denominator of first part by 2 we get 8/6 (what is legit operation on fractions)

Now easily add:
8/6 + (- 5/6) = 8/6 - 5/6 = 3/6 (here we can divide both nominator and denominator by 3 to get "nicer" result) = 1/2
